This is not what capitalism does. Much of capitalism today and in US history is that of a destructive force that hurts the entire population without consequence, enriching mostly the already wealthy.
The improvements and conveniences of modern society are unevenly distributed and brought to the masses at great cost to our society.
Unchecked global climate change due to infinite-growth-greed-capitalism has dramatically decreased the quality of expected life for much of the world's poor.
Capitalism absolutely does not, in theory or practice, make its benefits available to everyone.
