If politicians had to work in the same tiny cubicles in featureless office buildings that government workers typically have to spend their days toiling away in, there wouldn’t be any politicians.
If politicians were bound by the ethics rules that prevent all other government workers from accepting gifts or payments for services, they wouldn’t bother being politicians.
If politicians were bound by irrevocable law to spend no more on their campaign than one dollar for each person they sought to represent, there would never be any more politicians.
