A lot of people used the time they were involuntarily let go to up-skill into better-paying careers. This resulted in a labor shortage in minimum-wage jobs, regardless of unemployment benefits (that have since lapsed in a chunk of states). Market forces are at play here, there's no reason to special-case labor when small businesses can handle increases in the other costs (gas, lumber, aluminum, steel, etc), the only reason I can think of is because they think they can bully the suppliers (of labor), or lobby the government to do that on their behalf.
