No. If we can't make it work here on earth, where we have everything we need, how are we going to make it work somewhere else? Before going into the galaxy, we have to fix ourselves and our society. And we can do it.
Space exploration, i.e. NASA, takes up 0.6% of the federal budget, and decreasing. The Great Society programs, Medicare, Medicaid and Social Security, take up 54% and increasing.
So, be happy: as a society, we've decided that an extra 1% on grandma's pension is worth more than a Moon colony and humans on Mars (quite likely to have been achieved with double the space exploration budget).
