My comment wasn't about justice. It's about that when your country is basically destroyed: nearly all young men killed and the remaining population has their homes destroyed, you have all the industry and agriculture destroyed as well, it's very hard to make excellent consumer goods and personal computers for everyone. First, you need to rebuild the houses for the people, it's a lot of work. Then you need to feed the people. Then you need to restore the industry to give people jobs and prepare for the next inevitable invasion.
And BTW, despite all that, USSR invested a lot in development of those Baltic states like Latvia. Like really a lot. They were swimming in money compared to RSFSR or other republics (maybe only Georgia had the same level of allowance in the USSR). USSR built industry and power plants there, that they later happily sold for scrap after 1991. And closed fine nuclear power plant built for them by the USSR. Now they have no jobs, population is rapidly declining (during the "awful" USSR times it was growing), they have no energy. Good luck to them.
I think it was a mistake to invest so much in those states, one of the reasons for USSR decline. Russian people worked hard to make those Baltic states happy and now they are the most ungrateful nations saying only dirty words about USSR and Russia. Just as Georgia.
It seems the more you give to people, the more ungrateful they become. Just look at British/USA colonies: they still respect the master. E.g. Japan didn't invite Russia this year for the ceremony on the anniversary of US nuclear bombings. But invited USA. We joked: "Why the didn't invite us, but invited USA that bombed them? Because without USA this ceremony wouldn't even exist in the first place".
