Yes! Western states had to ensure that life was better in a Capitalist country. Hence unions were tolerated, along with human rights, rule of law, anti corruption etc etc.

Unions have never been tolerated - they seized what little power they have through actual economic force. The kind that no king or government can oppose for long.

Human rights and fighting graft don't have very much to do with the USSR, unless you ignore the centuries or history there before the Communist Manifesto was even written.
