At least here in Australia, a common comment on something like this is that we shouldn't spend money on this sort of thing when there are people starving and dying in the third world. Then the typical comments on, say an article about, the plight of the poor in the third world are critical of throwing money abroad when we have problems of our own at home. Then the typical comments on those problems (say, gap in life expectancy between that of the Aboriginal population and the average) find another excuse.
It frustrates me too. I'd love to see military budgets (as one example) plowed into aggressive space research and exploration (as well as third world problems) and uniting the planet.
Maybe the Great Filter of the Fermi Paradox is just the tendency of the masses towards selfish, lazy, basic instinct-driven behaviour.
