It has nothing to do with Trump. The FAA brought in the rule requiring 1500 hours and an ATP for a SIC Part 121. That meant that a High School graduate who wanted to fly in the airlines would have to find a job in something else at low pay for 8 years or so before even having an opportunity to apply for a job as a SIC in a Regional airline for 20K or slightly more a year. If a degree was included the time would be 4 years more and more debt.
So the inevitable happened and hardly any youngsters are interested in the career.
The airlines, with so few young'uns available, have resorted to going after anybody with more than 1500 hours so long as they can breath unassisted and giving them jobs.
There are precious few of them either, resulting in a severe shortage of pilots in the US and no sign this will ever sort itself out.
I run a Part 135 operation and cannot find pilots, any age, sex, experience.
Not good for me, and not good for you either, if I (and many others) go out of business there go the jobs.
