I am constantly bewildered by hostility towards space exploration in the public opinion. I really don't get it. Any time I hear "we should fix our problems on this planet first", I feel so utterly incapable of grasping the other guy's point of view that I can't think of any strategy to try and change his mind. The best I can come up with is prodding for how they feel about the amount of resources that humanity spend on consumer entertainment.
Most of the time they'll admit that spending billions (including tons of tax cuts) on movie remakes, overpaid athletes, and "AAA" videogames that nobody is going to remember in 20 years' time (let alone 200), is worse than spending them on making the things that let us have GPS and weather forecasts, or figuring out how to spot a dinosaur-buster in advance and do something about it.
But the next day, show them a trailer for Remake VIII: Return of the Revenge, and they'll just go "meh" at worst; show them a rocket launch and they'll actively bitch about the CO2 and how that money should go to starving orphans instead.
I just don't get it.
