Expanding NASA's budget by 2x or even 10x would not solve its problems. Parkinson's Law is as applicable to NASA as to any other organization. JWST and the other missions will overrun any amount of time and budget allocated to them.

I had that thought as I was writing the comment, which is why I added the word "current". But you're probably right to a large degree, and my only answer is that, to the extent that larger budgets don't decrease NASA'a fiscal discipline, the investment is better made there.
