Big Boom Versus Slow and Stealthy

 I think there's a spectrum of political change/reform, perhaps along more than one dimension, but at least one--scope.

For example, Biden's forgiveness of student loans is big in scope.  I'd guess it's one of the biggest changes in the student loan program in recent years.  (IIRC the Obama administration did some significant changes, moving more to a government-administered program.)

LBJ's Medicare/Medicaid program was very big in scope.  In the years since there have been smaller changes: the biggest I recall now is GWB's addition of Medicare option D--the drug coverage. Previously there was GHWB's catastrophic insurance, which got repealed rather quickly.

But it seems most changes in programs occur with smaller scope and less attention--the slow and steathy path.
