All the countries ruled by socialist, communist, whateverist left movements had only created misery.
Leftist Communist version of anarquism was never tried but my guts tell me it would be even worst. (and I have good guts for these things)
In west countries, leftist people are not specially talented but they always manage to get success for themselves and misery to everyone around them while claiming to be good, selfless and caring people it's all fake...they are just narcissist people that only makes something when it generates something for themselves, they have a lot of prejudices, they care a lot about what it seems and not what it is, they are superficial idiots, they use other's ideas for their benefit, etc, etc, etc
