SpaceX is also doing right now what Apollo and the Soviets are not doing right now. That's very important, because they are using modern materials and manufacturing techniques and developing new concepts. If SpaceX (and soon their competitors, hopefully) manage to keep themselves in business (and they might, because of the profit motive, which is enduring, rather than national pride, which comes and goes), there's a fair chance our species might bootstrap its way out of the ancestral gravity well this time around.
