There is $2.25T per year of savings to be had. We can eliminate our national debt in 15 years, and with that also eliminate the $1T going to $1.5T of interest payments we pay each year on the debt, so a total savings down the road of about $3.5T per year.
To put that in perspective, our entire national budget was a bit less than $4T pr year pre pandemic.
There is absolutely nothing else that comes close to the potential savings on healthcare. All of the schemes I have seen whether they are tax increases or cutbacks in other programs, even the extreme ones, *might* save $2T over 10 years.
