Sorry, but it is mainly Biden's policies. The administration has largely ignored white collar crime, especially when it comes to things like price collusion, antitrust, etc.
Case in point: the DOJ lawsuit against RealPage software (which landlords were using to collude on apartment prices). The company was engaged in extremely serious criminal activity, but the DOJ did not file any criminal charges.
It would also help to provide some type of calculation or explanation for how they even came up with that number. Reading the report, the 5% looks made-up.
