But the problem is still the "public" part of it. A private company can generally not put up red lights cameras and start forcing people to pay fines without direct cooperation with the government.
The problem is a part of the "public" part of it, not the public part itself. The problem is a weak government that could be corrupted by private interest. That doesn't mean you throw the baby out with the bathwater.
I'd be fine with red light cameras if they were owned by the government and it allowed police to worry about more pressing matters.
I think that a stronger government will only be more corruptible. The only reasons private interests try to influence government is that government has the ability to benefit then.
But the government doesn't optimize for profit, corporations do, and this is one of many cases (like with prisons) that optimizing for profit is bad for the world.
