Having never been to your country I can't speak to it, I trust though that this problem is probably more than just in the USA. When you have congress and women who have been in office for twenty plus years or more it smells to high heaven with the smell of greed and corruption. Once elected, the only thing that a politician cares about is making sure they get re-elected. The republicans had seven years they spent saying repeal and replace Obama Care and held more votes on it then I can recall at the moment. Then when they get control over the house, the senate, and have republican president to sign a bill to repeal and replace it they can't agree on how to do it. They need to go and it needs to happen this year, 2018.
We can't get rid of all of them at once as their terms expire at different times, but if not one sitting one of them who is up for re-election gets voted back in that will show them we have had enough and maybe some things will start getting done that could help get this country back on track.
