Oh, I don't know. Little things, I suppose: Not being able to enjoy the fruits of one's labors; lack of incentive; bad economy; government control of all aspects of life; suppression of freedom of speech, freedom of the press, freedom of association, and freedom of religion; widespread corruption; brutal murderous treatment of dissidents; human rights violations; the KGB; gulags. . . .
Like I say, little things, but they add up. Maybe I'm nitpicking.
"It's funny, really. They pretend to pay me, and I pretend to work."
