There's a theory that goes something like this;

"Americans over react to shocks like Sputnik, Vietnam and Japan's 1980s rise by coming out better and stronger".

So it will apply to Covid-19.

Problem is; the shock of mass shootings is yet to lead to sensible gun laws.

For many Americans, opposition to universal healthcare is a religion. When I look at the Covid-19 stats, it disproportionately affects urban areas, which tend to be more liberal than the heartland.

So conservative opposition to universal healthcare could be still left intact.

If this Covid-19 pandemic ends in the next few weeks, I don't see anything significant changing with respect to universal healthcare in the US.

The change will be more related to moving supply chains away from China and better disaster planning.
