They mostly do in the USA. Two exceptions: from international to domestic or international transfer must go through customs first, so there is a bag recheck and a checkpoint after customs (but usually not in baggage claim). Otherwise, people might buy a connecting ticket who doesn’t have a baggage transfer agreement with their first airline.

Other countries manage international to domestic without picking up your bag! There must be some way.

France does it by deferring customs until your final destination (so you might do immigration in Paris but customs in Nice). I’ve never seen that in another country, however.

Turkey does it too
