bribes is in quotes. There are a lot of questionable ways to do things that are not illegal. As the other post said, commonly it is we will give you a good job in a few years.
Even when there is a bribe it is typically hidden in something that looks legal. Buy something you need anyway from my brother-in-law even though you can get a better deal elsewhere. Family charities are a popular way for politicians to do this - most of the money goes to the admins the politician is related to. In countries we think of as corrupt there are typically direct bribes, but in less corrupt countries the question is how can you hide them in ways that are legal - often by doing things that fully moral people are also doing.
And once again, it's far easier to remove a regulator acting in such a way than a judge who serves for life and determines their own ethics.
