the problems you listed aren't pressing at all. alternative energy? we have truly ridiculous thorium reactor designs that could supply power (and run desalination off the back end for free) for the next thousand years. Space travel? Canned primates is a blind alley and we're ignoring more efficient designs because people are afraid of the word nuclear. Health? We actively prevent the falling in cost that would make health care more widely affordable, and that's granting that health care is related to health outcomes, which isn't at all clear.
No one wants to hear that all of our problems are self imposed. It's too terrifying given the current state of affairs.
I find it reassuring to know that, for many of our most dire problems, there are solutions out there. The fact that we're not using them doesn't mean we won't if we get desperate enough.
