> Laws against usury protect the poor.
Laws against usury subject the poor to illegal loan sharks who will break their kneecaps for non-payment rather than paying a high interest rate to a payday loan place that will merely ding their credit score and try to reclaim their loan money using the legal process.
> Laws against dangerous workplaces protect the poor.
Laws against dangerous workplaces protect shareholders from losing their investment when somebody gets hurt and sues the company. And give the company cover because they had their inspection done when somebody gets hurt regardless, so it's more difficult for the poor to sue them after an injury as long as their paperwork is in order.
Moreover, the compliance cost for companies that were not operating an unsafe workplace to begin with imposes overhead on small businesses and reduces competition, which can lower wages.
It's likely that they don't cause a major harm because there is no good reason to be operating an unsafe workplace regardless of whether there is a law against it, but they're still pretty close to breakeven.
> Hell, laws against slavery and debt prisons protect the poor.
Laws binding the legislature from instituting slavery or debt prisons, i.e. laws against certain laws, are not really canonical examples here.
> That's sort of my point, at this stage people just barely get by, which is exactly the sort of situation legislators can ignore.
We made things worse, but only by increasing inequality, not to the point of increasing homelessness. So we should make things even worse, that way when everything is really on fire someone will have to notice? What if we only get even more inequality and malaise?

> I'm not making an argument for maximising prosperity. A country with one quadrillionaire and everyone else broke would be the most prosperous in the world. I'm making an argument for protecting the poor.
The best way to protect the poor is to get them out of poverty. Giving all the money to one quadrillionaire doesn't do that, but neither does binding everyone's hands or making it more expensive for anyone to start a small business.
