Not impossible, however: No amount of changing the tax code will fix the real problem: Too Much Spending. That must be fixed no matter what we do.

I agree.

Let's say that we cut taxes and that results in an improved economy which increases the amount of tax money going to D.C. and state governments. Politicians simply spend that additional money. That additional spending may temporarily pump the economy into some 'bubble.' That yields yet more tax monies and more government spending.

Then the bubble bursts and we're stuck with the increased government spending and no way to support it.

That may not not be the best example but I think it gives the idea.

...and we're stuck with the increased government spending...

Right. They never think of that. Never.
When a family falls on hard times, they cut back.
Governments don't. They keep on plundering and pretend all is well.
In good times, they act like a lottery winner who buys a too big house even though they have no means to pay the remainder of the mortgage.
In bad times they buy votes by spending more.
