The inferences you arrive at from these studies just seem illogical to me.
These measures of cost don't demonstrate anything other than various bodies measure the cost of things for a variety of reasons. We live in a capitalist society that puts emphasis on economics, so it is not surprising there are data sets that measure the burden of the cost of absolutely everything and use dry academic language to do it! Sad to say human life often gets reduced down to balance sheets, we all exist as numbers somewhere and numbers don't scream.
We also measure the cost of lost productivity due to pregnancy. However, it doesn't follow nefarious legislation using that economic reasoning is then arrived at to deny people the right to have children just so they can keep working.
None of these studies is using their burden of cost findings to conclude we should deny people the right to die either. The very sources you cite don't reflect your conclusion. They actually call for improved continuity of care. Better access to community-based programs that can alleviate things from getting to a crisis point resulting in suicide in the first place. More attention paid to toxic work environments and how to reduce those stressors from occurring. All good things in my opinion. These studies seem to all be attempting to demonstrate the false economy of mental health provision not having parity of esteem resulting in greater costs in the long run to the state.
Sure it is unsavoury to use such economic reasoning to promote better access to care, but unfortunately, it is what governments listen to above much else.
Who also is this mysterious 'They' you are talking about?
If it is the government, you are giving them way too much credit. Politics by its very nature is divided and for the most part self-interested. Caught up in its tribalist bubbles inured to the ill-thought out policies they make that are rarely backed by evidence or backgrounds in the very things they preside over or meddle with. It comes down to ideology informing policy. Which I will touch on later as a more likely culprit, than cost burden as the reason for the denial of policies on the right to die.
However, if it does come down to economic reasoning. You could make a far more compelling argument for assisted suicide.
This is the social security budget of the UK from 2016.

The elderly draw state pensions. Which takes up a good proportion of the social security budget. The elderly are also more statistically likely to require multiple medical interventions creating a secondary cost to the state. As well as rely on costly palliative care in their final years. The elderly are also a demographic that is quite focused on their right to die with dignity and so if provided the options would likely take it. The dead don't claim pensions or use up medical resources. Thus a significant cost saving could be made both in the short and long term. This same reasoning could be applied to the disabled. Resulting in a significant reduction in cost burden.
I am not pursuing this mentality any further as it leaves me with the compulsion to douse myself in vinegar and want to scrub myself vigorously with wire wool until I have no skin left.
If the, 'they' you refer to is your employers. Then that also makes little sense to me. Because businesses suffer vacancies all the time and have contingencies in mind to fill the gap. Be it from pregnancy, suicide or heart attack, or letting someone go for sleeping on the job. They don't just sit idly and accrue lost productivity. They simply hire someone new and get on with things. On an individualistic basis countless business don't conspire, or even care to keep people alive against their will. Why would they when there is a readily accessible pool of equally disposable people desperate for work?
My personal opinion, the blame more rests on entrenched ideologies in political systems. In the UK, the people that wind up in the corridors of power and get to weigh in on legislation often have some religious background. Often elected because they mirror that same religious standard to the electorate and make a public point to do so. Eton for instance, still holds on to the importance of faith and instills that on its students. So they end up with those imprinted moral values. You only have to look at the front bench and how many of the politicians come from there or espouse religious sentiment. This is further worsened by the lords being home to ex archbishops and various priests and other faiths with similar absolutist moral stances on suicide.
All of this creates an environment where rational discussion on the right to die gets lost to ideology, and faith groups have pretty potent lobbyist with some powerful influence and campaign donations to withhold. I am curious if the USA has similar parallels?
If you look at the various countries that have active euthanasia legislation in place. They are generally countries with more secularist views both politically and culturally.
