I get your point, and it's a good one. I just don't think it'll work that way with space exploration. I don't believe that spending $trillions we don't have (we'd have to borrow it) will pay off enough to make that money, and the ten times more in interest we'd have to pay, worth it to the general public. As it is my kid will likely have to work until he drops dead at work (no retirement for future average Americans). We've been off course for a long time, and space exploration is part of that veering.
It's 1.4% of discretionary spending today. That's only the principal; another 10X+ is interest payments. Exploring beyond what we have explored so far (e.g. humans on Mars) would take it far higher.
Regardless, people like you are actually the reason I am thankful that SpaceX exists. It really doesn't matter to them what people like you think, thank FSM...
Do you really believe that spending trillions fighting for oil is somehow money better spent?? Do you have any clue how much the US blows away on airconditioning in Afghanistan?

It sad that people still believe Space Colonization is so pointless.
