If businesspeople want to get involved in politics, they should have the courage to run for office like anybody else. Lurking on the sidelines and waiving money around is really lame and laughable.
There ARE regulations for sure. But they exist to protect the population at large. For example, food safety laws were not created out of government hostility but rather because food was unsafe. Read (or read about) The Jungle by Upton Sinclair if you want to get creeped out about the food industry in the 1930s before regulations
There are people who couldn't care less about political power, but want certain laws passed, and have lots of money. And then there those who couldn't care less about much of anything besides gaining political power and see money and quid quo pro as means to achieve that.
The government is massive and inserts itself into business operations all the time. The inevitable results happen.
