You used the right word, Tom. "Fund". You fund things by paying for them - not by removing payments. This is a good 101 lesson for any Republican.
But onto your question - I have lots of good ideas (although I'm confused about this 70 trillion deficit you speak of) !
1) My main idea I stole from Republicans - make a simpler fairer tax code (except mine actually is simpler and fairer). All income of any kind is applied to the same brackets paychecks get applied to. That way scumbags like Donald Trump have the same tax rate I do and it drastically brings down the deficit. Much simpler. Much more fair. And Larry Kudlow gets to shit his pants on national TV. What more can you ask for?
2) Switch to a similar healthcare system as other western, industrialized nations whose cost per capita is between half and 2/3 of ours. And its paid for in a similar fashion. I understand this idea causes right wingers to have hemmoroid flare ups - but this is my answer. So I dont care.
3) Allow our government to negotiate drug prices like every other entity on the planet.
4) Outlaw the concept of "dynamic scoring" so scumbags in Congress cant tell us that 3-2 = 4
5) Give the Pentagon unilateral authority to cancel any defense projects it deems to be unnecessary so scumbags in Congress cant award bullshit contracts to other scumbags that fund their campaigns.
This is a partial list.
