A lot of people suffer from Selfish Laziness. Too selfish to consider anything except their won ego , and too lazy to put too much effort into anything. It has to be understood that humanity does have empathy, what it lacks is compassion. Humanity has a very selective empathy, as in they only have empathy for people similar to them, so humanity tend not to be able to put ourselves in people's shoe's. Unless they are similar to them in some way, or if they can relate to them in some way. Especially if they fit the " norm.' of society( nice, handsome, no mental issues,)
There are a lot of people trying to do good in this world, and might even be succeeding in small ways, whether through individual acts or collective action, unfortunately those people's efforts can sometimes be counter balanced by the cruelty of the world. Plus those people are often quieter about their efforts and don't usually get the attention they deserve because its seen as boring and evil and destruction is seen as sexy and alluring. Plus these people get dismissed as " not practical." and " not realistic." a lot in our world, and " doesn't bring results." even though they usually bring a lot of results(I've personally seen it myself, with an organizations slowly bringing in a lot of Food gardens throughout the community, especially poor areas and even colleges) unfortunately this does not get much attention in the media, which would've been very useful for these types of efforts, inspiring others to do these Fleet Farming projects throughout the country. As well as many other societal efforts that would've been good for individuals and society at large just simply not being considered because its not something that's " seen." or " gives immediate results."
So there's a lot of good things going on, and genuine people trying their very best, unfortunately those actions either doesn't get the attention it deserves , or they are quickly ruined, hijacked, and outright destroyed by viscous people/institutions. Then these same type of people who destroyed such good efforts are praised( even from those who are supposedly condemning them) are praising them for their " cleverness." there " shrewdness.', there " Machiviallism." and there use of " power." . So these people are often times praised for their awful behavior, especially if it gives them " results." ( monetary gain, weapons, art.). Our world see's selfishness and ruthless as the default setting, and seems to suggest that it should always be that way, despite claiming otherwise often. Revealing how people often times care more about results then the morality of actions( Roman Polanski is still being praised as a great film director despite being a rapist, Elon Musk is praised as a great inventor despite abusing his employers and refusing to pay them, cheating and abusing his previous wives and stealing the company of Tesla from those who actually started it originally. Steve jobs is praised for his invention and founding Apple, despite abusing his employees, exploiting workers in India and other countries and abusing hos own daughter and treating her like pawn even Hitler is praised occasionally for his " clever" for his actions, and these are from people who are not Nazi sympathizers by any means ).
Plus a lot of people don't wanna put that much effort into things, even if they can. and even for the smallest. While a lot of people are simply to busy trying to pay their bills and not become homeless to even think about the world beyond their own(especially if they have a family to feed). There is a lot of people who simply chooses not to, even if they can ( one dude admitted to me that he would walk away if he see's someone being killed in front of them for a Genocide, even if they were crying for help, my own family covered up a possible sexual assaults' by my uncle at his own niece in order to not cause problems in the family, even though my own mother was a victim of sexual abuse herself). So a lot of people, even when they are in a position to do some good, often times, simply decide not to do so because they don't see much benefit from it. Only doing nice things if it helps their ego and/or reputation so that they can feel good about themselves and/or humble brag it too other people. The ones who are genuinely kind and trying to do good have no need to do humble-brag or anything. Like that( as an example someone who presents herself as kind and sweet, evening showing a video of herself giving her nephew a FIFA video game for his birthday, was someone who abused and raped her boyfriend despite him begging no when he was at pain the most from his leg injury and have drugged people in the past to have sex with them). While I know these are extremes examples, its to help so that a lot of people in society are really egocentric and only put effort into things that will have immediate results/gratification.
Society( and a lot of people in general) lack patience, hence the laziness aspect of their selfishness. That lack of patience and desire for immediate results has caused a lot of personals and world-wide conflict over the years. A lot of people love conflict and causing crap to hit the fan because it helps with the boredom and makes things more exciting. Or even simply can't help themselves because again, lack of patience and desires for immediate results that's directly beneficial to them. Hence a lot of people have a zero-sums game mentality. The world as it currently is, on all levels, are based on the exploitations and sufferings of others, and frankly a lot of people like it that way( and the people who don't are giving very little faint attention, nodding their heads empathetically, then turning around and doing more crappy things.).
Its easier to destroy then it is to create. Its easy to destroy lives then to create them. Its easier to bully then to discuss. Its easier to bomb a country instead of making peace talks( which is why people like Abiy Ahmed, who actually won a Nobel Peace Prize for the Etrician-Ethopain peace deal and ending the border conflict after a long-time war that left a lot of deaths, are so far and between nowadays.) . Peace, compassion, and everyhing related, takes too much effort for a lot of people, and is seen as unrealistic ,and even weakness. Hence destruction, pain and suffering palys too mcuh of a role in society. And some of us like it that way.
Humanity is capable of creating a better society if we truly desire to. So is not a matter of can we. Its a matter of will we. And the answer seems to be No. Or at least No unless it takes little effort as possible.
