Stupid kids saying stupid things
Also, Uncle Sam is in debt to the tune of 21 trillion (or was 120 trillion), growth exponential. Yeah Humans on Mars. That's gonna fix things,
“The United States has been a leader in human space exploration for more than five decades, and our efforts in low Earth orbit with our partners are approaching maturity with the completion of the International Space Station."
The US has FAILED at human space exploration and the ultra-expensivy gypsy hotel in orbit is not "approaching maturity" unless you count permanently imminent plans for deorbiting as "maturity".
The only thing that "the US" (more like JPL, amIrite?) has been good at is robotic space exploration. It brings the bacon home. That's want you want. There is no point firing bacon into faraway sandy lands (it might even enrage people of certain religious tendencies).
