“Large corporations have an enormous of power, but their power is nothing compared to that of the government.”
Money buys power. Corporations can afford to, and do buy whole Governments and Countries. It is not the politicians who are benefiting from our National debt. Follow the debt chain up the ladder. The power is in the hands of those who buy the elections and put these politicians in office. Those like Gates, Soros, and Zuckerberg. And even they are just Sargents in the chain of command.
And power controls the money.
It's a chicken or the egg argument.
The best way (I think) to understand it is to look at countries that have fallen prey to a dictatorship. I can't think of one which has fallen prey to a corporate dictatorship.
In fact, in most emerging dictatorships, corporate boards are abolished and reconstituted with government puppets.
