I'm not sure what it really says about the current state of human pragmatism / cynicism that everybody expects any career politician to have certain levels of corruption.
But speaking as an outsider, I think we can safely say that if/when Biden takes office, while he might populate many of those agencies with some elements of those lobbying fields, he wouldn't be as blatantly obviously brutal about putting people in charge of the agencies that try to keep their personal interests to some form of legal accountability.
Of course, it actually puts me in mind of Tom Clancy a little. President Ryan's "I'm going to pick people I personally know and trust who are experts in their field to be put in charge of x and y..."
I wonder how much Tom Clancy Trump reads....
