Stein is right on some things and wrong on others as usual. He is right that this nation has obligated itself to pay for huge entitlements no politician will touch. We can yap on the sidelines about balancing this and cutting that but the fundamental problem is cast almost in stone by generations of politicians - right and left. Medicare and Social Security are huge obstacles. No politician(s) will get the votes to kill these entitlements since so many people depend on them now.
The only partial answer I can fathom is to at least privatize part of Social Security. That one IMO is doable - although difficult as we saw that a Republican WH and Congress couldn't get it done. This would help at least one program.
