I think it's more interesting that so many of the most popular scifi series are socialist. Star Trek etc
I don't think it's so much as socialist, as capitalism is partially obsolete in the face of high technology, and the basics of life being unlimited and free. Instead of capital, people strive for self-improvement to gain influence and power in society, they become artists, scientists, athletes, explorers, Starfleet officers etc. It's a meritocracy instead, which is sort of a system we do have in parallel with capitalism today, where the most famous and influential are not necessarily the most wealthy, and vice-versa. Although there is a significant correlation, it's far from absolute.

Sorry, I don't buy that for one minute.
Take a look at America's "underclass." They have more leisure time, better healthcare, more food, and thousands of amenities that did not exist among the richest humans on the planet 100 years in the past. Yet, the market economy is still with us and it provides us with all we need and most of what we want.
Because it is not the nature of the market economy that is the central issue, but
human nature. "A luxury once tasted soon becomes a necessity." Truly, it doesn't have to be tasted or seen.
It only has to be known to exist for someone without
it to covet
it and resent those who have the means to obtain
it.
Until we become gods and change the fundamental nature of humans, the market economy will best serve humanity to motivate useful activity, distribute what is produced, and foster innovation.
