Wow. I’ll bet that’s a huge part of it.
I think another part is that while on one hand, distribution of resources and decisions about closings, curfews, is all happening as though each state is an independent, sovereign entity, but interstate travel is still happening as though the US is a single nation.
We shouldn’t be trying to have it both ways. Either each state should be operating as sovereign, with the ability to close, or at least stringently regulate its borders, OR there ought to be a stronger centralized national leadership.
I realize that people worry about transporting goods from one state to another presents problems, but trucks could be driven to borders, and the trailer decoupled from the bobtail, connected to a new bobtail from the neighboring state, and the trip continued. That way, the truckers themselves wouldn’t move from state to state. If very careful sanitary measures were taken in packing trailers in the first place, and again when they are unpacked, transmission that way would be minimized, and at any rate, the chances of Covid-19 being transported in the air on on the goods in a trailer are pretty slim, since the stuff is in the trailer usually more than 24 hours. The concern is more for the bobtail and the truckers themselves.
If the trucker observes social distance, and is the only one to touch the bobtail (barring it needing mechanical work) you minimize the risk of truckers carrying virus from state to state. It doesn’t take all that long to decouple and recouple a trailer.
I can think of other ways on minimizing interstate travel. Any lots of the interstate travel happening now is happening for non-personal reasons, and much of that can be stopped with relay systems like this.
We really have it backwards, running the states like independent nations, but traveling like the US in one country. We should be treating the states like independent nations, but running the US, at least in regard to a Covid-19 plan, as one country.
It’s really a problem unique to the US, though. The Canadian provinces, I don’t think, have the kind of independence that the US states do. Even when there was a Soviet Union, and the SSRs were former independent nations, they didn’t have the self-governence of the states. They may have been homes to people of separate ethnicities and languages, but they were much more subject of the Supreme Soviet than the US states are of the Federal government.
