My position is simple and has 2 parts:
To expect anyone to create meaningful regulation on every sector of the economy is absurd, our system is far too complex.
We need regulation if we want to live in a safe & healthy modern society.
Unless you just disagree with the second proposition, it seems your implication is that every congress person should be an expert on every sector of the economy and fiscal policy, and be able to craft meaningful laws, or at least have strong opinions about them. Otherwise, they would just be accepting laws written by other people, just like delegating to the regulator.
Corruption exists in every system. I grew up with clean air and water thanks to the current regulatory system, and have benefited from a safe work culture my whole life. Best I can tell the only guy who has really done anything to stop that is the current President, so kinda a crude characterization to say that they change with every admin.
I never implied congress is expected to be experts on everything. What I do expect is a level of scrutiny much higher than what is considered rigorous by academic standards.
It should not be a hard ask that regulatory bodies produce meaningful, thoughtful, and extensive uneditorialized reports on a subject. These are then given in summary to congress who can use this information to inform regulation.
This strategy is superior for a few reasons:
1. It keeps regulatory bodies honest and when held to the highest possible standard of scrutiny works to prevent a lot of trivial gaming of the system
2. It separates the powers appropriately. Congress can ask anyone to do research and return results. This is not the same as providing an unelected body defacto law writing power.
And on the final point regulation can be good. I think it's dishonest to interpret my position as anti-regulation. Rather, I think regulation is trivially corruptable. Regulatory capture is the mechanism by which the largest wealth-having class maintains their power. Regulatory capture is trivialized through the use of Chevron Deference (see my post above). By cleanly separating the two we reduce the probability of corruption. If a corrupt politician can't inject their stooges to defer to then we have an extra mechanism by which to protect our rights, and protect our health. It then falls on congress to do the right thing. Then it's OUR responsibility to elect people who will do that.
If we allow for the assumption congressmen are not idiots, are capable of reading and referring to experts, and act accordingly then there should be no meaningful difference modulo preventing unelected officials from writing law. If we cannot guarantee that, then it's not corruption, it's a complete failure of the legislative branch of government and the election system. Which I think we both agree here in one way or another that the system has completely failed.
