Under the approach Thomas lays out in his Sackett concurrence, the federal ban on child labor is unconstitutional. So is the minimum wage, federal laws protecting the right to unionize, bans on workplace discrimination, and nearly all other regulation of the workplace. Thomas’s approach endangers countless laws governing private business, from rules requiring health insurers to cover people with preexisting conditions to the ban on whites-only lunch counters. And even that is underselling just how much law would be snuffed out if Thomas’s approach took hold.
