"We all die, and when I die, what I can't pass in the estate I do hope goes when taxed toward the national debt so we leave a clean slate for the next generation."

You have way too much faith in the government.
The government already taxed that money, it's not fair to tax it again, and certainly not at such heavy percentages.
Eliminating the estate tax would actually result in more tax revenue, just as every time income tax rates are cut, the government ends up with more revenue, as a result of economic growth.
The government taxed the money once, but they never collected for the national debt and I think we should be good conservatives and not pass on our debt to the next generation.
The tough part as you say would be in seeing to it politicians don't go spending the incredible rise in income that will come to the treasury as lots of people become old now and die.
