There's already been a big issue with 'regulatory capture' and lobbying in government.

Congress is only going to delegate when some other entity, likely a business, isn't already writing the law/regulation.

A concrete example: Boeing is going to up their lobbying game hard. They can now not only help write the laws, but help choose who says they've broken them. There is no way that it will be good for passengers before it is good for stockholders.

This is done with the regulatory agencies now, i.e. the revolving door from government agency to private sector.

Worse, in some ways, because there's no real paper trail, such as donations to politicians or PACs.

Bribes to politicians rarely include paper trails, Super PACs don't either. The problem of vast amounts of dark money in politics is well documented.

Good thing people from Boeing and Goldman Sachs aren't working in these agencies now, making these rules for the advantage of their former/future employer.

Good thing Boeing hasn't already been doing that /s

Burning a man alive with a stubbed toe: "He was already injured!".

Yes. Lobbying is already a huge problem. This ruling exclusively makes it worse.

How is it worse that now they need to lobby Congress instead of just getting the FAA to say that they can certify their planes themselves?

The fact that Chevron has been the law of the land for 40 years means that Congress did intend for it to continue to be the case. It’s ridiculous to claim otherwise.
