That should be the title of this superb Kevin Williamson piece at National Review about the subject, of, well, not spending money you don’t have, and how Donald Trump, whatever his other found virtues, is really really bad at not doing that.

So many pull quotes – and all have a theme:

Stop spending money you don’t have, dummy.

The last time we had a surplus, tax revenue was 18.8 percent of GDP and spending was 17.6 percent of GDP. That was 2001. Taxes were even higher as a share of GDP in the two years before that: 19.2 percent of GDP in 1999 and 20 percent in 2000. I prefer low taxes, but I don’t remember the tail end of the 1990s as an Orwellian dystopia. If the estimates hold, this year, revenues will be about 16.3 percent of GDP and spending will be 21 percent — with deficits forecast as far as forecasters can see. And that’s while the economy is doing well. Either that tax number moves or that spending number moves — or we have deficits forever, until the creditors call us on our bullsh**.

At which point we will have no choice but to:

Stop spending money you don’t have, dummy.

And when they blow that?  Well, Williamson’s on that subject, too.
