I believe that modern living is not compatible with fundamental happiness. Happiness is always going to be an acutely subjective topic, but I believe it's possible to narrow down a universal, basic human happiness to factors such as having purpose, being healthy and having meaningful relationships with other humans. I would take the evolutionary perspective on most issues and say simply that we are socially evolving too quickly. We have not adapted past a nomadic lifestyle yet. Furthermore, purpose and meaning is so unique to each individual that you need time and space to cultivate it, but we can't because we are thrust into this idea that we must work to death and THAT will give us purpose. Work for money. Work for material.
This ties in with these grand notions of capitalism and neoliberalism and whatever else at the base hook of materialism. The pursuit of wealth, and through that, power, has remained exactly the same since the time of monarchs. If you compare the power structure to kings of old, it's exactly the same. Where you have a power of one or few over many, you still have the power of one or few over many. Kings, presidents, corporations, barons, sultans, lords, ladies. It doesn't matter. It's just all about money, material, wealth and therefore power.
These systems have not changed in essence because there is no invested interest to change them. There is no change because the comparison exists between you and a billionaire. If you ignore quantity and circumstance, you can easily bypass any scrutiny by just saying, "well you need to work harder".
You are fed a lie from birth, essentially. Work hard and you will achieve great things. Contribute and pay your taxes, you will be rewarded. It is a false promise, for a start. Secondly, and more important to this discussion -- it won't bring you happiness because we are not wired that way. Your fulfilment doesn't come from someone else. It doesn't come from serving an abstract notion of a system. It is yours and yours alone. Failure or inability to grow that results in depression or worse.
So the system is flawed, to begin with. It is unchanging because the powerful hold the keys. The lie that it is founded on means that you will never have fulfilment. This becames very apparent in times of economic, political and social strife, like 2020 for example. Some people are more sensitive to this than others. That's human variance. Some people are smart, some people have shitty lives, some people have opportunities and never have to confront this problem until their midlife crisis. Ultimately though, we all get depressed. We all lose our way, because our modern society is built that way to serve the few. Who cares if a few people kill themselves if it works? That's the logic. If it isn't broken, why fix it?
This is abhorrent of course, but that's where we're at. We're unfortunately stuck between times right now. We are on the cusp of significant change or significant more-of-the-same while it all falls apart. I personally believe that the only solution is to kill the rich, plunder their dragonhoard and re-assess our legislation at a fundamental level. Gandhi was the modern mans biggest mistake. Peaceful protest does nothing when you're dealing with psychopaths and they are psychopaths. The only way is violence. Enough is enough, you know?
