If we amended the Constitution of the United States to state that only corporations count as people then our politicians would no longer be lying when they say they support the people. We would finally be living in a country in which the peoples' will is done and be a country in which the peoples' voice was regularly heard.
This issue is a good example: not “all politicians” are selling out citizen for company profit. There is one party that restricted predatory practices in lending, and the other party is now rolling this back.
I know there is plenty of criticism for every party, in every country, ever. You will never find a politician you completely agree with unless you run for office yourself.
But this specific example shows there are, indeed, two vastly different options available in US politics.
