Well, let’s face it, Trump has been a space cadet his entire life. So, it wasn’t that he avoided his service obligation, it was just that his branch of service hadn’t been created yet.
But in the real world the Republicans have tax cut us out the revenue needed for basic first world necessities let alone have the funds for a space force. Hell, we have to use Russians rockets to get our guys up to the space station, and communities have to have donation drives just so that teachers can have simple school supplies.
The US is a rich nation, but those with the bucks aren’t reinvesting it in America thanks to the work of their GOP shills in Washington.
