Unlike you, I bet, I actually visited communist Eastern Germany and the Soviet Union as a student back in the late 80s.
You would not have liked it.
The tapwater in our hotel in Leningrad was rusty brown. The air quality was so bad I had black stuff coming out of my nose when I blew it every evening. Black market guys were offering me a lot of rubles for the Levi's jeans I was wearing... still not sure how that would have worked, getting back to my hotel in briefs? The tea, the bread and the candy was decent. All the other food was horrible: One night, one girl from our class started sleepwalking and when her friends stopped her she said: "I wasn't going to eat anything, I was just going to have a look at it" because she was traumatized by dinner.
Alcoholism was a huge problem in both the Soviet Union and Eastern Germany, affecting life expectancy.
And the DDR was a nation of spies. I suggest you watch the movie "The Lives of Others." We had relatives in the East, and I actually own a Stasi file that mentions me when I was 4 years old because they had opened the birthday gift my aunt had sent me and typed out the content of the letter word by word and made an assessment on whether that was a suspicious delivery.
Yes, capitalism has huge problems. But even as somebody who grew up somewhat underprivileged I have to say that most instances of late 20th century and early 21st century capitalism beat the hell out of any communist state, ever. And I think our German system, "soziale Marktwirtschaft" which you also have in many EU countries, combines the best parts of both systems and allows for the most dignified lives of the citizens.
