Not that easy. In USSR 'success' could mean anything - you could be a good doctor or a good teacher, a good factory worker even or a good scientist. Now 'success' means only one thing - money. Sell your mom and dad, sell your own soul, but get the money and be successful. That's the main problem. In some other countries it may be possible for a doctor or a teacher to earn good money and be content. Unfortunately it's impossible in present-day Russia, and that's what people miss about USSR.
