I would agree that almost certainly plays some part. Less than half of Americans have $1000 in the bank, according to quite a few surveys over the last several years. People are broke 🤷♂️
Considering you need a couple handguns, a rifle, a shotgun, and then your other gear for CAS, that's a fairly high entry bar these days. Then throw in ammo and gas on top of the gear... it adds up.
