Why would you use the term unelected beuracrats when the Supreme Court are unelected beuracrat? Seems weirdTo be clear, Chevron deference had nothing to do with the relationship between the departments and the president, and very little even to do with the relationships between the departments and congress, and was almost entirely the relationship between the departments and the courts. When Congress passes vague laws, the enforcement agencies have space to interpret how to enforce the law. This is still the case. Chevron deference was a standard that said in a situation like that, if someone takes the government to court over said enforcement claiming it violates the law as written, the courts would defer to the departments themselves to tell them what the law is. Getting rid of that means that the courts will have to do their jobs and interpret the laws that Congress passed, not defer to the unelected bureaucrats that are being sued to decide the legality of their own actions.
The enforcement agencies were already beneath the president's authority, taking power from them also takes power from the president. Gutting Chevron weakens the Presidency.
The office of the president can use the courts to force the agencies to do exactly as the president says. The 'failings' of the Trump presidency has mostly been placed on 'agencies not doing as they were told' and taking things to court to defy the executive. This is meant to stop that
Eg. The DOJ SHOULD be an independent body that falls under the executive. If a president makes an EO that clearly breaks the constitution, they could go to court to make it not valid. Now they can't. And now they gain the extra benefit of turning independent, impartial bodies into partial entities
What you are talking about is true. It's just not all of it. Because that part you are describing is just the benefits to those funding this decision. Eg. Uber, Facebook, Google, Telsa, petrol companies, Coke, Pepsi, Purdue etc. They want unfettered deregulation so they can do what they want. Congress won't do anything because they are paid not too. They aren't here to represent the people. That's not taking into account that Congresspeople don't have a science background so any bills that get through are solely about identity politics rather than actually fulfilling on policies
It's like Reagan ripping of the solar panels off the White House. He was just an indentitarian who was paid to do it and it was never about the economy or what was best for America
