Aren't there many such states? Otherwise known as "free" states?
My home state of Florida is a "right to work" state; it's also a state where you can be terminated for any reason, or no reason, which is perfectly reasonable. Barring a formal contract, nobody has an unalienable right to hold a job at a given employer.
No employer should be forced to hire or retain any employee, barring a binding contract which specifies the procedures by which issues are resolved.
Isn't such common sense the norm in the United States?
Right to work states are probably no worse than other states for the discharged employee. Yes, they can be let go on a whim, but if they are, they’ll get unemployment benefits.
If they are fired for cause, as defined by Florida law, then, of course, they can’t collect unemployment benefits.
But folks need to understand that the right (or lack thereof) to a job is a different issue than the right to unemployment compensation.
