>> (during Brezhnev's time, GDP went into guns and away from butter).
Is there any empirical evidence supporting this?
There were many improvements in the life typical citizen in the 1964-1982 era, a lot of better housing(which means more people were able to leave villages for cities, which had infinitely better infrastructure), in my city countless facilities were built in that era.
>> The kids were different, they began to have access to cartoons and other cultural experiences from the West
The cartoons mentioned in the article are Soviet cartoons. Access to Western 'cultural experiences' was more or less present from roughly death of Stalin to start of Perestroika. French films were frequently shown. I think after 1988 or so Western entertainment production flooded the Soviet Union.
>> and began to question why they had to make do with so little
That's an interesting take. For example, 'kids' in SU had access to free healthcare and higher education, and a better quality high schools, which the West didn't provide to it's citizens.
And the WW2 devastated USSR and there was no Marshall plan.
And, for example, Imperial Russia had GDP far below US at 1913 (So these countries were much poorer then the West to begin with)
In any event, why should people feel happy about living under an oppressive system -a system which stunted their potential?
I don't think 'oppressive' system is something that has a clear meaning. There were restrictions on travel, on starting and owning the businesses, and political life was structured differently from representative democracy. For some people it was fine, for some it wasn't. As is the current marriage between capitalism and representative democracy.
>> Their "police" were soviet milicija, so in a way they lived under occupation to booot.
Baltic countries were indeed under occupation. They were integrated into Soviet union by military force, compared to other republics, which 'joined' the SU as a result of civil war. That explains that fervent Baltic anti-communism, because socialism was always something brought from abroad, from Russia, something basically not needed.
"milicija" is just a term for police, so that has no relation to occupation.
