Therefore we should never talk bad about it or look in to alternatives.

I can think of at least one (Northern European style Socialism) that is better to live under via virtually any metric for 99.99% of people - and that includes the majority of users of this site that think they are some sort of tech unicorn.

Just not having insurance tied to employment would be such a massive win.

A: That's not socialism!

B: What is it then?

A: It's free-market capitalism with good regulation and a comprehensive social welfare system.

B: Well, let's do that!

A: No, that's socialism!

"We" - humanity.

"We" actually experienced all social systems "we" invented so far, which are allowed by "our" productivity.

Humanity did fine with other systems that capitalism. Hunter gather societies were well adapted to their environments, Tibetan monks dealt with human relations differently etc.

It would be crazy to assume that the whole humanity longs for capitalism whatever their situation or belief system, the same way _we_ don't assume any current form of capitalism is specially superior to other alternative forms that could better benefit our situations.

Openly and fairly regulated capitalism, yes.
