Not too long, unless we can get the illegals to go back home and stop more from coming. That will get us some time, but what with gov't subsidized poverty breeding programs, the future is a third world society with a thick upper crust, a huge lower class, and a much smaller middle class. Eliminating welfare would also give more time.
My wife at the public hospital sees this mess first hand and wonders where to go once the tipping point is reached. I have no answer for her. So we invest heavily in the kids' education right here & now, because when the rotted structure falls, I doubt currency will avoid hyperinflation. Saved cash will be inflated away, even cash saved up to put the kids in college.
But, yeah, if Texas goes tango uniform, get ready for the (even more) authoritarian regime.
