Much of what is portrayed as special interests buying influence can be seen at least equally accurately as politicians extorting money from businesses.
For example, when government threatens to interfere with business by enforcing border security business has to protect its access to illegal cheap labor.
Surely you jest. The profitability and even existence of businesses is always in jeopardy due to government regulation or persecution.
Many tech companies used to not contribute much to campaigns. The classic example is Microsoft, which used to be proud that it didn't contribute to or get involved in political campaigns. Their reward was an anti-trust prosecution that was remarkably flimsy.
Does anybody seriously think they would have been prosecuted if they'd contributed heavily to Clinton's campaign?
So guess what all the tech companies do now? They contribute heavily and get accused of corrupting the process. If the government didn't have so much to do with whether a business was allowed to succeed, they wouldn't need to have influence.
