Fantastical that you feel the need to compare something designed in the 70's to something newer...I guess window licking at spacetwitter is a full time job...

If you say so. The broad point is that we have evolved to the point where profitability is an option. And regardless, there was an inefficient bloatedness with the shuttle program.
