That's your opinion. I'm not saying there's anything wrong about it, but it's just that a modern capitalist government's priority is to make sure its society stays stable (unless you think its priority should be to seek chaos) because that's what governments were built to do--to provide stability.

What you're not taking into account is macroeconomics. When you let anyone do whatever they want, it is very likely that the rich will get richer (because they are more informed) and the poor will get poorer. And with that comes corruption. That's why the government steps in to break off organizations that become too large and make sure things like antitrust don't happen.

If you think the society is unjust, first try to learn WHY things work that way, that way you may either come up with a solution that can solve it, or go build your own nation, or at the least understand what's going on.
