meh - real stuff that people use is what the gov should spend money one. Not to mention that the bulk of the IRA infrastructure spending ends up in the pockets of middle class construction workers. But in terms fiscal impact, IRA spending will start trending downward further out and be a decreasing economic effect.
FTM, a lot of defense spending also ends up with middle class workers also, but a bridge or internet backbone project leaves something more useful behind that a weapon system that hopefully ends up someplace like that Arizona airplane graveyard (I say 'hopefully' because that means it didn't have to be used in a war....)
