>Some people tend to believe governments are the root of all evil.

I can understand their thinking and know how their logic works. They see horrible wars and injustices done by governments - therefore, governments are evil. Problem is: this is too shortsighted. I think a slow shift towards more liberty and less government is the only way a libertarian society can every be achieved.
Any sudden revolutions won't do any good. People need to want these things for themselves or it will fail.

>huge public companies are bound to become evil unless they are controlled ... by some kind of government!

Hm. This is something I disagree with on a theoretical level. The current political system protects big companies via tax reliefs, subsidies, minimum wages, etc. I never understood the logic of people who complained about corrupt governments and their liaison with big companies - and then wanted to make said government more powerful.
The more tools of control you provide, the more likely it will be, that someone is searching for opportunities to manipulate said tools to his own advantages. But if these tools are rendered useless, the incentive to do so decreases.
Hayek coined a phrase for that:
>"Capitalists don't like capitalism."

Because as soon as you "made it", you like to have a strong government behind you which can protect you against market competition.

The problem is not with democracy per se, the problem is that our "liberal democracies" never democratized the economy. Unless you democratize the economy political power will be invariably coopted by, basically, the 1% (what you describe as crony capitalism, but which is just capitalism).

You can control corporate power with regulations as you suggest, but we have seen what happened after FDR: corporate power was shackled to a degree but it started a slow but steady attack and is now wreaking havoc again. Capitalism cannot be shackled, it will undo any regulation given enough time. The real way to combat corporate power is to prevent them from being so powerful in the first place, ie. democratize the workplace, democratize the economy.
