I think we should simply relocate the Capitol of the United States to somewhere like Kansas or Missouri. Turn DC into a huge museum, but move the actual government to the middle of the country. Get it as far as possible from the coastal elites -- that'd help quite a bit, I think.
In the process, force a change with all politicians. In other words.....all of them must be changed. Along with that, change our laws back to what they were 50 years ago. A complete change to what the people want....not what the politicians want.
