See this is your big misconception. I am not arguing from a point of "putting people out of work". But, that being said, NASA should not be a jobs program. Part of the problem with NASA today is that it gets so little bang for the buck because of congress using it as a pork barrel jobs program rather than being concerned about results. You want to keep those people in work? Make space cheaper and open up the market. Get enough companies interested and you'll have a shortage of engineers for all the work available. I truly don't understand your obsession with Huge launch vehicles. I mean seriously, you think it would be practical to send up a ring station in one piece? You know, I don't have a problem with HLV's. I have a problem with overly costly HLV's that waste money that could be put to better uses.
