What some may not realize is that the "power corrupts" goes for capitalism as well (not discussing if "power corrupts" is always but admiting as if it is mostly correct).
At the same time that there are powerful dictators with powerful families, there are powerful superrich companies, superrich individuals and their families.
A place where the wealth is very concentrated, where the income is centralized in just a few hands, have less freedom, more crime and more corruption. This is not theorical, but rather statistical...
Gini (inequalty index):
Corruption perception index:
International Homicide (the darker blue, the higher):
Press Freedom Index:
There are some exceptions like countries in North Africa, but all these things are connected somehow although I dont know which causes which. Admiting that power corrupts, which I have some doubt on that phrase, the highest the Gini, the more concentrated the income is, there is more concentration of power in a few hands, lending to corruption and ultimately leading to less freedom. However I do believe that concentration of power is sometimes a natural event in the course of increasing corruption, rather than a cause, depending on other condition (this analysis can get quite complicated). The exceptions of India and north Africa are the reasons I believe that.
In the end of the day, there are connections between these powerful people...
Stalin and Czars werent much different, they were all totalitarians in some sort of form. Czars and some quite bad kings over middle age are connected the same way.
In countries where the superrich are the most powerful in comparison to general population (that goes for a higher Gini), there are less freedom, which make them "more totalitarian". In the end, the super rich guys are connected and are pretty much the same as powerful communist partys. Latin America followes pretty much this pattern, with dictatorship coming and going, besides being capitalist or communist, pretty much corruption and a lot of superrichs that concentrates a lot of power.
So in the end, Stalin and his family and 'pals', Czars and their "nobles", hyper-rich people, its pretty much the same pattern.
It is quite funny that people who defend the super and hyper rich as an opposal to communist think (or better, pretend, I believe most are truly aware) that, because most communist regimes are totalitarians, they are defending freedom and are being "libertarian", when they are actually supporting totalitarism in a different form.
