I do not agree with Igor in demonizing the "capitalists". Capitalists (or rather, finance) have done everything that we see around.
Why Igor, who criticizes the "capitalists" in such a way, doesn't run to build houses, supply water or give food to the poor? And you, too, are in no hurry to give your money to a good cause. It turns out that we are no better than the criticized "capitalists". We may be unhappy with the state of affairs, but there is little we want or can do.
In fact, the reason why it is impossible to provide everyone is simple - the available resources (in a broad sense) are not enough for this. No one wants to work for free, food does not fall from the sky, houses do not grow after rain, fresh water suitable for drinking (especially where there is a shortage of it) also does not appear out of thin air. Providing one such region with water (houses, food) for decades to come, and not just giving everyone a box of conditional Coca-Cola is a very, very expensive project. All this time, people have to work for free, or someone has to pay for operation and production for tens of years - this is hundreds of thousands, if not millions of people. Nobody needs a conventional box of water, because they will drink it and the situation will remain the same. No one wants a home, no maintenance, no electricity and no sewage. No one needs food for one day, it will either run out or deteriorate.
Therefore, water and food are produced and houses are erected where it is profitable, where you can start a production cycle that would at least pay for itself ... Capitalists create jobs, ultimately pay people wages in exchange for what people produce. Others consume. All these billions of dollars, which, for example, belong to the richest people in the world, is not pure money, it is just a third-party appraisal of the property or its shares that they own (including factories where people work). If any of them thinks to sell everything sharply in order to provide other people with food, water and houses for free, he will dramatically lose in capitalization and it turns out that he does not have much money to do such large-scale projects.
All capitalists have foundations that do charity work in various fields. They do a lot, but so far they cannot do everything at once, like ourselves.
In fact, the number of the poor (in need of food, water and a roof over their heads) is steadily declining and will continue to do so. I think soon robots will replace workers and it will be much cheaper to build a decent house, at the same time, more people will have a roof over their heads. The same processes occur with the price of food and will continue to occur for some time.
With water, everything is somewhat more complicated, here I do not presume to argue, but as technology develops, I am sure this problem can be gradually solved, if not, then loosen.
This is hindered by certain circles of stakeholders. Capitalists have only one goal in life - to fill up the purse. And what kind of makar and with what general consequences - this is the saddest thing. They pay attention only to what makes a profit, and not how much, but a lot and quickly. And the contribution to technology or at least charity only takes them away.
