The reason blue laws were done away with is b/c imposing a christian day of no business on people violates the rights of others who observe a different day.
Instead mandate that every business is subject to blue laws twice every seven days, and let the business choose which days - and they will be legally bound by that choice and can only change it once every two or three years.
Meanwhile, days like elections that should have blue laws, don't. All state and federal holidays, and all election days, should be subject to blue laws in addition to the legally mandated two days a week (not in place of). American corporations need to be brought to heel.
I'd also like to see retail/service work weeks required to be blocks of set schedules, either 20 hours in set 4 hour daily blocks: eg 9-1, 2-6, 7-10, or 40 hours (ie 2 set blocks). It should be illegal to require overtime, have zero hour schedules, or irregular shifts. Not exploiting workers is more sustainable.
