Lol if you think income tax funded those things you are seriously misinformed...
They were funded by the "federal" reserve
That debt is being paid back through user fees like gasoline tax
You think gas tax revenue is fed money?
Avoid the temptation to homogenize treasury and fed to make a point. Tax revenues fund our domestic spending and are managed by treasury. Fed loans to private entities qualified for the prime lending rate. Fed's QE has expanded that role after the housing bust but not for stimulus. Stimulus went toward our deficit and ultimately our debt.
Gas tax goes to roads but doesn't fully fund roads. That's why our roads are so poor in many places of the country and why we mandated gas taxes exclusively for road repair and construction.
