That's not an assumption,
it's literally what happens.
I can even use a case study that I have brought up several times before that you
also refuse to acknowledge because it doesn't let you maintain your bullshit.
When Kansas cut taxes thanks to Brownback and the Conservatives, the result was an explosion of the deficit. That deficit forced cuts to social spending, specifically, cuts to education. Because of those education cuts, the State Board of Regents had to increase tuition for in-state residents. Now, what does that mean for the students and their families? That means they had to take out loans, or take out
bigger loans to cover the increase in the cost of tuition thanks to the drop in revenues, thanks to the tax cuts.
So that's not "unfounded"...that actually happened. That is what we refer to in the business as "empirical evidence"; namely, evidence you can observe yourself, with your own two eyes.
