Why immoral? Genuine question - if anything surely the premium processing is immoral as it pushes other (innocent?!) workers further down the queue?

It's better to have recourse. Either everybody waits a ton of time, or some people barely wait and some people wait a ton of time. Why drag everybody down to the lowest common denominator because of "fairness"?

Are we all not (potential) workers that would improve the economy? This premium service does not protect against national threats.

This has nothing to do with Trump, or national threats. No F1B holder is superior to the others, but I'm glad that there's a way to jump the line if you have the means.

This along your other comment in this thread is the definition of 'classism' and how the income gap widens.

Attempting to frame opposition to lowest-common-denominator-politics as a equivalent to racism and other -isms with a word made up by sociologists is laughable. A Porsche costs more than a Toyota. 2-weeks processing costs more and uses more resources than 9-month processing, and you can pay for it if you wish. If everybody paid the premium fee, then USCIS could hire more, and everybody could get it done in 2 weeks. Couldn't be fairer. USCIS is entirely (99%) funded by applicant fees, so this is literally how it works.
