I am not sure this assertion holds up under historical inquiry but that's my opinion.
No, this is not Marxism. I can't even claim to have ever read his books. It's the reality of what I see today. Note that I'm not saying in any way how we should solve these things. I'm neither smart enough to think of those solutions or naive to think they'll ever come to life. But it's undeniable that we live in a dire world and capitalism is one of the biggest forces behind it all.
Peace? Seriously? Of all the things you could cite from capitalism, you mention the one thing that never stopped happening. Perhaps war stopped nearby your home, but capitalism never brought peace to the world. On the contrary, it created many, many wars. As it's often said: war is profitable.
Innovation is a tricky one. I agree a lot has been brought because of the pursuit for profit, but I believe they are happy coincidences. Many of the worlds greatest brains are today trying to find out how to exploit people through ads.
Perhaps your personal experience makes capitalism the lesser evil compared to the soviet USSR, but I'd urge you to not fall into this false dicothomy. It's not a binary choice.
