I think your question is overly broad, there were and are many types of government and they all had different effects. I don't think it's even simple to answer if one government is a positive or negative. Was the soviet union good? millions dead, censorship of other ideas, huge leaps forward in quality of life on some axis, killed more nazis than the allied forces, forced the usa to get to space -> which meant some of the technology people living in the ex-soviet union exists now, it's existence encouraged the granting of worker rights/higher pay through fear of similar upheaval.
