It is not very pleasant to have such an aggressive neighbor at hand, especially when this neighbor declares a plan to join NATO at the level of his constitution.
Maybe it's not very pleasant for Ukrainians to have Russians as a neighbours. Were they or any post-soviet countries satisfied with being a part of soviet union? No, so they want to get away from but you want to keep them so the war has started. If the quality of life and other criteria were high in Russia, I believe your neighbours would wish to be with you.
Why this conversation when you ask about the meaning of life? Moreover, it does not matter what your standard of living is, if you do not have sovereignty, if you are not free. Russia has sovereignty, but Germany does not. Germany is occupied by the USA. If you have a better quality of life than in Russia, then you are just a prosperous slave. For Russians, freedom is not an empty phrase and definitely not a bargaining chip to buy access to spotify with it. Think about it at your leisure.
I think I feel more free in Germany than in Russia. When I was there in late 90s/ yearly 2000s when I was a kid, it was not safe there. There were a lot of drunk people in Moscow streets, Milizia was constantly stopping my father and mother and they were releasing us after getting some $ from us. And it was happening very often.
I have some good memories from there too, one thing to say for sure, there was a huge respect toward me, toward kids and children in overall. I was white and a little blonde with blue eyes, so when my mom or father was with me, they weren't stopping us or if they would stop and I would start crying or would look afraid, they were immediately going away from us.
My father is a very honest person and in Russia he was working as an engineer, but before that, as a builder. He was working with serious people and he was very appreciated for hard work and honesty. But outside of work, milizia was always trying to get money from us, can say the same on criminals in districts, so we were charged from both of them.
