I agree, but I also think a significant fraction would not. I'd expect a lot of markets to crash and burn, as people quit for various reasons, with a lot of knock-on effects. I'm not sure how it would turn out, I just feel like the world would be turned upside down.

Now it could end up being like war-time economies which boom due to high demand for military goods, in this case for all the work needed to build a space colony. But in a war, at least people can hope to live on.
