Transportation and housing (for example) are parts of the critical infrastructure of a community. Allowing decisions about those things to be made entirely by the (relatively wealthy and mono-cultural) owners and customers of those businesses is unfair to the other people affected by those businesses. Hence regulation.
Which, again: There are bad and stupid regulations. Of course. But regulations are useful tools, overall.
These two ideas are at odds. The rich are doing fine for themselves. The people we need to go out of our way to make sure we're helping is the less wealthy and the less powerful. That's whom the government should be advocating for.
But in balance. Businesses need to be allowed to flourish, as well.
And, by the way, you benefit greatly by having the government have a say in your life.
[Edit: I believe I misinterpreted the bit of text I quoted from you. Apologies on that. But my general comment stands.]
It might not be true generally, either, say if the advantage wealth provides outside of government is greater than the advantage it provides in government. That rich have disproportionate influence in government doesn't mean they don't have even more disproportionate influence outside of it.
I like regulations because they're guidelines that help us operate in the best interests of ourselves and the public. And they prevent our competitors from acting immorally or dangerously to get a business advantage (which might force us to have to take either make the same immoral/dangerous moves or shut down).
Bad regulations are bad, of course, but regulations empower businesses when applied correctly.
