Incredibly so as the US is politically corrupt, but not in the way people normally think about corruption. Lawrence Lessig wrote a decent book on the frame of this calling it Gift in Kind corruption, rather than Quid Pro Quo.
And then if you magnified this beyond the US context vastly harder to create an international framework where this is enforceable and upheld without loopholes causing breakdowns.
Seems a common sense idea with wide and necessary applicability, it is worth reviewing and understanding historical things such as the smoking and social media lobby to grasp the extent to which the task run deep, particularly with respect to political funding and manipulation.
