It might seem like it's not a thing from an Australian perspective but it is definitely a thing from a global perspective.
Skywest have more jets than Qantas, Virgin, Tiger and Jetstar combined, and that is only one regional. Count all the others and you realise how huge the scope of aviation is in the USA. Think you can look up in the sky here and find out where the guy above you is headed with flightaware? Wrong. You will see a sea of aircraft going every which way.
In the USA it is going to be a huge problem, more than what it already is. Regional airlines hire at only barely above the rate the the majors suck pilots out, plus flying schools are closing down from lack of students. You can come over here with .1 above the mins, all on a 152 if you so desired, although you do need 25 multi, and get straight into a jet. Only to get command in under 2 years in some cases.
It's also pretty good for a stint: Full, unrestricted ICAO ATPL. No bonding. Sign on bonuses. Leave whenever you want. Renew your visa indefinitely. Jumpseat on any domestic flight.
