Nope, those are the wrong experts. The correct experts correctly warn that destroying our economy is what will doom us.
Do you see what you just did there? You surreptitiously conflated two entirely separate and distinct concepts, expecting no one to notice. I nonetheless noticed. First you were explaining how spending is what will doom us ... and then you quietly shifted to our debt alone will eventually become too much of a burden.
Don't worry, I won't tell anyone.
Next time, go for the whole box of cookies, i.e. start with "out of control spending," then stealthily shift to suffocating debt while pretending that you haven't changed topics, but then pretend like you've been decrying crushing taxation the whole time as what will be the end of us all, and before anyone realizes it, you "conclude" with how overprinting of fiat currency and hyperinflation will sink the ship ... and finish with "and that's why we need to control spending."
Do you really not see how stupid this idea is?
