It cost $100 billion between 1995 and 2001, according to the Commerce Department. So, a bit under $17 billion in spending per year. That's significant, but in the context of an economy worth about $10,000 billion, at the time, we're talking about less than one fifth of one percent. It's about equivalent to the stimulus of building a single aircraft carrier. And it's not like that was putting to work unemployable people. It was putting to work people who'd have had jobs doing more productive coding if they hadn't been fixing old oversights.
If the economic footing wasn't solid, how do you explain how resilient that economy was? Remember, even when the first of Bush's recessions arrived, it was unusually short and unusually shallow, and even the additional knock of 9/11 didn't extend it much.
That's not so much a fact as a tautology. You just said a bubble created a bubble. Do you mean the dotcom bubble and Y2K created a larger bubble in the economy? If so, that's not a fact, it's an assertion. If you have support for the assertion, I'd be happy to listen to it. But, keep in mind there are ALWAYS bubbles happening, of one sort or another: gold, real estate, bank stocks, bitcoins, beanie babies, etc. When an economic boom happens that doesn't fit with right-wing economic religion (e.g., the Clinton boom, following the upper-class tax hikes), there's a strong urge to explain it away with reference to bubbles, etc. But the mere existence of a bubble doesn't create wider economic prosperity, or we'd always have prosperity, just as we always have isolated bubbles. Putting a few thousand old Cobol coders to work isn't enough.
He raised interest rates to fairly high levels at a time of low inflation. It was either political meddling or incompetence. Either way, it brought about a recession.
