I fundamentally distrust these people (on both sides) which will make it hard to not presume there are perverse incentives in these bills, but I’m open to it. My sense is that antitrust is as wrong a model for correcting this as the prior regime was that led to the creation of antitrust laws.
I trust them to respond to incentives, chief of which is to do things they think will keep them in office. The problems come when doing right by their constituents is no longer the biggest thing that keeps them in office (e.g. instead of outspending opponents on marketing). Or when there are incentives that are hidden from the public.
You do know that for many of them they have a virtual lock on their seat and the incentive no longer aligns right?
For some/most, the primary driver can be characterized as self advancement.
