well, we need a LOT of changes. For example, I agree with the Republican tenets of lower/fair taxes. The problem is, that they then follow it up with massive tax breaks and do not cut spending. 

Then we have Dems that point out that we have to do spending in civil areas, but then go all out with the money. It is just INSANE. For example, I like the idea of provinding inexpensive undergrad/grad schooling. But, when I suggested that all 18 y.o. should do boot camp, and then get a free semester of schooling. Upon the end of it, they get money back based on grades. 
Get a  3.5 and above, you get 100%. 
3.0 and above and you get 90%. 
2.5 and above, you get 70%. 
2.0 and above, you get 50%. 
The idea then is that you can either work for the missing part, borrow, etc.
