Blame the Solar System.
So far, we haven’t found anything in our Solar System that justifies sending humans to live on other celestial bodies permanently. We can certainly do it, if we’re willing to spend the money with no hope of a positive return on investment. But the U.S. is broke. We can’t afford any more ventures like that right now.
Today, we’ve already sent unmanned robotic probes all over the Solar System. We can learn whatever we need to know that way.
