I believe it was Thomas Jefferson who was most opposed to intergenerational debt, because one generation could hoard wealth (mostly land at that time) and then future generations would be indebted to the dead, which goes against the spirit of liberty and justice in the United States:

It basically comes down to: a child should not assume the debt of its parents in a free society. Some more info on the founding fathers' views:

I'm generally left-leaning, but here are some articles from right-leaning publications for anyone fearing "fake news":

I agree with your sentiment though, that soon we'll have to make a choice as to whether to assume the debt of our parents or raid their assets to pay it down.
I also feel rather strongly that if children shouldn't inherit their parents' debt, then they also shouldn't inherit their wealth. The best way to accomplish that is a high inheritance tax. I know that people object to this as an impingement on liberty, but we have to also consider justice for the broader population (as I've written about in my previous comments).
And I also see your point that if we inherit infrastructure, we should also be ready to inherit debt (so that's perhaps not inherently unjust).
But I'd just like to also point out that I've never seen the federal government vote to raise taxes to pay for the national debt. The debt went down briefly under Bill Clinton, but that was mostly through reducing welfare expenditures (which arguably later backfired, as experienced by people whose benefits ran out during the Great Recession, among other things).
So I am also very skeptical that it will ever raid bondholders to pay for the debt, although that could explain the (cruel?) sentiment to destroy social security, medicare and medicaid to pay down the debt by republicans. Again, I am very skeptical that that would work, because prior experience indicates that they'll just give that money to the very wealthy and we'll still be left with a large national debt.
