That's a good point, but the increased visibility should act as a deterrent. That's why it's not OK for a President to have a sidepiece anymore, when back in the day it was a matter of course.

All of us are more aware of what comes up when someone googles us, that we will be judged based on what's out there.

Or perhaps it's just the money. One does not have to be a good citizen if you are loaded. Social contracts and norms are for losers. And, since Trump assembled the richest cabinet in U.S. history, it only makes sense.
