"President Trump's abrupt and unexplained decision to summarily remove over 40 U.S. attorneys has once again caused chaos in the federal government,"

Unlike when Clinton and Obama removed even more.

Article quoted biased, rubbish criticism from Democrats who know that a vacant position will better enforce the constitution than the socialists that were fired.
Prosecutors do not only follow the law, and as you implied they decide what laws will be enforced and to what extent.

I am unclear how how these "anti-business" regulations come into being. My understanding is it starts with some problem that's being handled by the courts like loud music or chemicals from one property finding their way to someone else's. So the gov't comes up with the idea they can reduce litigation this by making regulations that set limits and penalties for these scenarios. The trouble is people lobby their representatives to craft the regulations in a way that favors them and hurts their competition. This causes everyone to have to lobby. Representatives generally don't claim to enjoy that their job involves so much fundraising, but they don't have much incentive to change it. It's easier to take the money, have the lobbyists help create the legislation, and make it look like they're "doing something" about important problems.

Is anyone in this system "anti-business" or "pro-business"? I definitely encounter people who I would describe as anti-business. By that I mean when someone's doing well they think someone must have stolen value. They can't conceive someone built something useful. This strikes me as childish. I wonder if elected if these attitudes find their way into laws passed or bad regulation comes mostly from the scenario I described above.
