It is so often I meet people arguing that capitalism is broken, capitalism is a "exploitation" and that we are past the scarcity era, so, we can throw capitalism away and reorganize economy in the new arrangement, where each persons basic needs are fulfilled and there is no more extremely rich people on first hand and tremendously poor on the other.
That sounds nice, very optimistic and so empathetic, but this is total bullshit, since there is no easy way to solve the problem of scarcity in economy. Many people are thinking in that way: there are so many of goods here, on the planet, much more than people actually need, so why don't we just put all of them in to one big, global redistribution process and give each person what he needs?
That is point of view of someone, who never studied economics and has only good intentions and no actual knowledge about what the price system and economic calculation means. Unfortunately for such kind of idealists, post-scarcity economy is an utopia according to the actual scientific knowledge. I could argue here about Conservation of energy principle, entropy, one-way arrow of time or alternative costs, but I'am going to point it down as simple as I can.
When you see that there is so much food wasted on the one side of our planet, and awful famine killing children on the other side of globe, you can feel that something is wrong. And it really is, but the capitalism is not a part of the problem. Usually places, where people starve to death are not capitalist countries of abundance (which is USA for example), but the third-world countries, ruled by the brutal dictators, military regimes and torn by tribal conflicts (like Ethiopia for example). There is war, there are bandits, there are corrupted politicians, ideologists killing for religious reasons and no trade, no production, no agriculture, no free market, no capitalism at all. So, as you can see, it is not the restaurant owner in Paris throwing unsold food to trash guilt of famine in African countries. There is politics and war, what you should condemn.
Going back to the scarcity problem: economy is not the issue of redistributing goods, since there is no such thing as "common pool of production and goods" which could be divided and redistributed among population.
Many people would like to consider that economy is like strategic military plan, when general relocates divisions to the place, they are most needed from his point of view. But it is not like that.
Each person on the planet do or does not produce something or provide services to others. And everyone who do produce something is rewarded for his work - it is another question if the payment of particular worker is "fair" or not, but I'am not going to start this topic here, maybe another time. So as you see, we have no homogeneous pool of resources and goods, but billions of separate, private pools, with their owners. So you can not just relocate resources in to new way and solve problems of some people.
Problem of poor, starving people in Africa is that the politicians in their countries prefer to use international charity for funding their luxuries and waging their wars, and the western politicians prefer to establish protectionist trade policy against African farmers (check the EU importing policies). The capitalism has nothing to do with all of that.
So, when you see that there is a famine in African country, and the shop owner in you neighborhood puts food in to the trash bin, there is no connection at all. Do not blame your neighbor nor the "capitalists". Believe me, or not, but if some capitalists would be able to start enterprising activities in that poor, starving country, people there would become slowly richer and happier. As it is in China, where 1 bilion people leaved extreme poverty last decades thank to the capitalism.
Remember: economy is not about relocating divisions, and politics is not about helping people and solving their problems. Most problems we've ever had, was caused by the politicians, as wars, economic recessions, environmental disasters and many other.
