So far, most space endeavours are related to science in some way. which is problematic because there is little to no return on investment. also, everything we have and consume is on earth. I can't think of many products which are low in mass but extremely high in value and could benefit from the only properties of space we control right now; weightlessness and orbits. To me, cheaper rockets could only help building a future space elevator which would reduce costs significantly but we would still need something to do in space. So what do you think the first economic incentive will be to enrich society?
