Basically it goes like this:
Republicans: We want more power so we can make sure the government is fiscally responsible and morality is enforced
51% of America: Ok, that sounds good
Republicans: Just kidding, thanks for electing us. We wanted more power so we could make ourselves rich and be evil and leave you all out in the cold.
51% of America: Oh no
Democrats: We want more power so we can make sure you're taken care of.
51% of America: Ok, that sounds good
Democrats: Thanks for electing us. We're going to take care of you, and by that we mean we're going to decide everything you can and can't do and exactly when and exactly for what reason and you don't need to make any decisions and you CERTAINLY don't need your constitutionally protected right to keep and bear arms. Why do you need anything when the government is here to provide for you? We are your mother. Your father. Your everything. Embrace the collective.
51% of America: Oh no
Libertarians: We want the government to have less power so this nonsense stops
97% of America: But if we all vote for you, we've wasted our vote!
Republicans and Democrats: Yeah, you'll waste your vote! We want more power.
97% of America: Ok, I guess we'll just keep doing that.
How do you define "as long it doesn't hurt anyone else"?
The right to swing my fist ends where your nose begins, is the commonly used phrase.
