For all my dislike of capitalism, there aren't many better systems. Perhaps capitalism leavened with some socialism (public roads, police, health care, etc.)
The last hundred years a number of political systems has been tested.
Compared to how almost every single communist experiment has ended, - and also nazism (far fewer examples but for some reason I really don’t want that either :-/) I far prefer what select lucky European countries and USA as well has done. Specifically I really think the European democracies has almost nailed it with reasonably good public health care, reasonable taxes all while still allowing and encouraging competition between for-profit companies.
"The advantage of communism is that everyone is equally poor. The disadvantage of capitalism is that some people are richer than others." - something I heard as a kid
"Many forms of Government have been tried, and will be tried in this world of sin and woe. No one pretends that democracy is perfect or all-wise. Indeed it has been said that democracy is the worst form of Government except for all those other forms that have been tried from time to time.…"
i.e. what most rich western societies have.
