I don't understand why we can't all be happy with euro social-democratic levels of spending done at the state level, with minimal federal spending for military, justice dept, and programs that 80+% of the population agree with (~10% GDP). You don't hear Scandinavians petitioning for a Euro wide healthcare system (the equivalent scope and scale of Obamacare). This way progressive/liberal states can still be happy with their programs, while conservative states can keep their taxes low. This is the philosophy of 50 experiments on what is good government policy. I just don't understand why Americans feel like we can impose our values on everyone else. We live in a free country, and people are free to immigrate to a government that aligns with their values. We don't need to solve this at the federal level.
