Trying to make illegal the paying off of politicians only skates the root problem that you have a society where enough wealth is concentrated to enable the buying of legislation from supposedly democratically elected representatives.
Even if you managed it, you still have an absurd over concentration of power and wealth you aren't doing anything about, that just continues to corrupt at all levels of society.
