re: Key word: SUSTAINABLE
The problem is without clear and real public support non of this VSE will make it thru the next administration no matter how much of the CEV is completed. And it doesn't matter which party the POTUS is in.
We have a debt and deficit which are ever growing and a war in Iraq which we can't easily exit from and is not winnable. And worse the War costs hundreds of billions a year! The USA economy can't sustain this for long and again space is just another program to cancel because of fools.
