A good portion of the problem is that people can't spend the money. They can't get a haircut, they can't get the dog groomed, etc.
Just think of the lead times: 1) Govt needs to source 100,000,000+ cards...every two weeks 2) Govt needs to source the correct envelopes 3) Govt needs to load the cards with cash and program a semi-unique pin on every card 4) Govt needs to make sure the right cards get in the right envelopes.
I think the experience with things like the healthcare marketplace online app, the rollout of PPP, and the mere sending of a single check to 2019 taxpayers should provide a cautionary tale about how difficult it really is to implement seemingly easy or good ideas.
K.I.S.S.
not trying to be a negative nellie...I just don't think something like this is feasible without extensive lead time.
