Really!  And how has the US private sector managed to do that given incomes are subdued, hence benign inflation.

Honestly, the internet is awash with tripe. Latch onto doom-mongers at your peril!

There is only one set of data to consider when considering debt - that is inflation.  The Fed, as all CB, have a mandate to keep inflation in check, create conditions for economic growth and ensure stability in the economy.

Government debt is not the same as Dave's mortgage down the road.  Doom-mongers prey on the naive that got boggled-eyed at big figures.  Money can be extinguished just as easily as it is created.  We'll know/if there is a debt problem when inflation breaks out of a 2-3% target range.

There will be a recession eventually, that is normal cycle and easy to understand why it occurs.  When it happens there are opportunities not armageddon.
