So no apartment buildings?Here's a fourth, commercial entities cannot own residential property except for controlled exceptions. Hurts liquidity but also keeps prices and monopolizing low.
How about... stores with self-checkout machines must have at least one paid attendant working at the register for every 2 machines. No more having a dozen automated checkouts with only one cashier. Or maybe a law that you must have at least one cashier with an open checkout lane for every self-checkout machine that is turned on. So if you want to have 10 self-checkout machines running, you must also have 10 cashier's lanes open at the same time.
Another one... companies with 20 employees or more cannot use automated answering services (ie "press 1 for X"). A live person must be hired to answer the phone or any calls you receive must go straight to voicemail. Also, maybe the phone answering person would be required to be located domestically, as in inside the country where the call is coming from.
One more... no more self-serve gas. New Jersey already does this and its fine, so it can definitely work.
I'd love to hear thoughts on these because stuff often sounds good when its just in your head, but then people can point out obvious flaws you might have missed.
