The only thing preventing humans from building an outer space colony on mars is a lack of imagination, amirite?

I think its lack of funding and most people are greedy misers, but i see what you're saying.

If by imagination you mean political will, then yeah you're absolutely right

I would rather say lack of unity and willpower but yeah, that works.

Just build a really big rocket and point it down to push the earth out into space like that one episode of Futurama.

We need to build a wall on Mars to keep those Mexicans from getting there and taking our jobs dammit!!
