The current tax cut increases the national debt during a good economy. So this irresponsibility limits America’s options when this bubble (if it exists) bursts.
This time is not different
Half of those cuts reset. The primary item in the other half, the corporate income tax cuts, were a necessity to compete with the rest of the planet that has a more typical ~20% rate (including Europe, which has the lowest corporate income tax rates of any region).
The deficit is going to $1 trillion, the tax cuts are an average $50-$75 billion per year of that problem over the next ten years.
The tax cut is meaningless in that picture. It'll add at worst a trillion to the $30 trillion pile of public debt that will exist in 8-10 more years.
Good luck to the US. The yearly budget is $3.8T. Of that, only $1B is discretionary. $3T of tax cuts is three years of the entire discretionary budget. The cut is huge. And that cut wasn't Keynesian stimulus - it came during a good economy. Good luck to the US.
I'm not sure the dot-com boom and bust affected the rest of the economy nearly as much as it affected our industry. If there was a recession, it was the smallest in decades:

It was a modest recession, but it wiped out a huge amount of wealth held by "main street" investors. It was bad enough that Bush, a very, very pro-business president, signed into law the Sarbanes-Oxley Act, which is widely criticized as an onerous and needless regulation by conservatives.
