The US does in some sectors! But this traces all the way back to when two competing union organizations in the US (the AFL and CIO, before they merged) had major beef about how unions should operate. In the end, the CIO's model mostly won out. It would be really hard to do sectoral bargaining in the US because there are vastly different costs of living across the country but each state is required to have free trade with each other. So to have New York workers bargaining for Alabama workers or vis versa would be a disaster. It should also be worth pointing out that countries with sectoral bargaining also have huge number of self-employed and sole enterprise people. France has something like 2-3 times the number of self-employed people, and my understanding is that it's one of the only ways people in these economies can "opt-out" of bargaining agreements.
