Sorry... it's a no from me. I think the worst thing about communism is it inhibits people who are willing to put all on the line to succeed.
I think it's bad in the sense that it usually seems to turn into a dictatorship.
I think communism and capitalism are both bad, because both use coercion. The only difference is who is doing the coercing - the state, or the rich/market forces/people's own need for things like food and shelter and everything else? It's the use of force either way. And in both, the purpose of your life is determined for you - to be productive. You're not really free to determine your own purpose in life.
Then again, the question is,
can everyone succeed? What if you weren't born smart? That's not really someone's "fault". It's hard for me to support something where some people are just screwed no matter what, and it doesn't matter what they do, because they just weren't born good enough. They say you're supposed to "make the best you can with what you have", but what happens when "the best you can" still sucks because of what you were born with? Or in most cases, what you were born without?
The thing I don't like about capitalism, is that it makes a lot of things into "faults", when that isn't necessarily the case - like the brains you were born with, or the interests or personality you have. In capitalism, there are "right" and "wrong" ways to be, despite them saying you have "freedom". I mean, technically yes, you have freedom. But when most of that "freedom" is only theoretical because following it only leads to misery, you're a lot less free in practice.
Now that I think about it, there's a lot of parallels, and overlap, between being the kind of person who succeeds at capitalism, and being "cool". And to some extent, attraction too, for that matter.
Another thing capitalism does, is make people follow whatever makes money, and not their true interests - or even to take the time to figure out what your true interests might be, or who you really are at all. So you wind up with a lot of people studying subjects that they never would if they really had the choice, just because they need money and this is what pays, even though they're not really good at it and not really interested in it. And they probably don't even do that well at it either, because it's hard to force yourself to study things that you aren't good at, and don't find interesting.
The way the world is now, STEM is pretty much the "right" answer. But what if you weren't born with a STEM brain? Or the interest in it?
That's not really a person's "fault". It's just how they are.
