Certainly not. I'd rather see taxes lowered, so people can make their own decisions about how they want to spend their own money.
I'm perfectly happy to live my life on Earth. If they suddenly colonise Mars, and it's fantastic, and it makes you live twice as long and have superpowers, I would still rather stay here. I'm simply not interested in it.
People often cite the technological advances - "velcro" etc but I don't think you're getting value for money if that's your aim, and again, I think it should be done in the private sector rather than forcing people who have absolutely no interest in space, to pay for it.
