I honestly would just pray for the US citizens right now and hope that Trump actually makes a move worthy enough for the title of President. You can basically describe the position of the government as stuck between a rock and a hard place, and continuing, the government instead of trying to get out, is actually just making it basically worse for them by making themselves more and more stuck in there. It's like a juggling act where they're forced to use one hand cause they tied the other hand up themselves.
I don't think this is a question of protests, racism, and police brutality. Those things won't cause a shutdown, but serious health risks like COVID-19 already did cause one and certainly could again. Imagine if the mortality rate of the virus was higher and people were absolutely terrified of physical contact with each other. Imagine if the government had to force people to go back to work. We'd be in some serious shit at that point, and IMO we lucked out with the coronavirus because it could have been much, much worse.
If the virus was actually worse than it is right now, I doubt governments of various countries would have allowed it to spread this badly. But sadly, it wasn't, and that was probably the point that allowed it to spread this wide. They probably thought they could curb it easily, considering how it is transmitted.
