$15 Trillion is not the fault of the average citizen.
Look at the revolving door between corporations and the government,
and the lobbyists greasing palms of the pirates of the Potomac.
The national debt is actually about $100 Trillion if you count unfunded liabilities.
Worse yet the global derivatives bubble is north of $1,500 Trillion
which dwarfs the nation debt, this is being unspooled all over the planet,
but that chicken will come home to roost before its all over.
1st tier reason has been due to ppl getting rich off the
military industrial complex and its 700+ bases in 100+ nations.
2nd tier reason I'd place on sending millions of jobs overseas,
and then creating 73 different types of VISAs to import cheap scab labor.
3rd tier reason is when the imported labor wasn't enough they intentionally
ignore the issue of illegal immigration and 30+ million illegals swarm the border
and take all the manual labor jobs.
4th tier reason, they add poisons to the food, water, and drinks intentionally
and cause most of the nation to be physically ill., thus running up medical costs.
Some of the poisons listed here:
GMO, RBGH, Fluoride, Mercury in most corn syrup, MSG hidden under 24 different names,
Asparatame, toxins like thimerisol/squalene added to Vaccines, etc etc...
These medical expenses often send families into bankruptcy.
Additionally they hide the multiple cheap cures for cancer, and that sends families
into bankruptcy as well.
Millions of citizens of the US are under intentional attack and do not even know it.
They carve it in the guidestones, Pianka says it in speeches, Holdren writes it in his books.
Killing off the population slowly and making money off it all at the same time.
