I'll be blunt: I find this thread a rather embarrassing way to portray USA.
1) the thread title is misleading; Wendy's doesn't take burgers off the menu. Only in "some locations"
2) underneath that sensationalist piece is a part that is actually relevant: "The closures have halted 25% of pork production and 10% of beef production in the U.S". That's certainly not insignificant, but also not crucial either.
3) Seeing that this is (apparently?) caused by 4200 ill workers, it is actually a case AGAINST reopening the economy rather than for one.
4) OP also implies that the USA was apparently dumb enough not to consider food production, transportation and distributing as an essential service. Luckily, this got torpedoed later on
5) that last link isn't talking about the USA. I know I've made the analysis that the USA is screwed, but let's not go nuts, okay? The USA isn't a developing country (yet), and it's not like "my local Wendy isn't serving meat anymore " is somehow a complaint of the same category as "on top of draught, crop failures and locust swarms our village now ALSO faces dire consequences in food distribution due to the corona virus"
Okay, and perhaps 6) link your sources directly rather than through a google result. It proves you weren't triggered by news events but rather pursued them to prove your political agenda. But I'll be fair: that's just a pet peeve compared to the rest.
Still...despite all this, the last part is worth discussing:
"Is this a warning? Should we open the economy soon?"
(well...the first one. The latter one is pointed out that it was never closed to begin with)
I'll be honest: I have no clue how food distribution works around the globe, and upon inspection it actually SHOULDN'T work. I mean...I had avocados for lunch today. The whole world's in lockdown, but somehow this vegetable gets to travel the world to get on my plate?
Some countries I know like the Netherlands have made it an honor case to be self-sufficient in times of crisis, but Belgium has always relied on exports. Our agriculture simply isn't strong enough to feed everyone. For the moment it's okay, but I have no doubt there'll be a major impact somewhere in the not so long future. Our (little) agriculture relies for a large part on immigrants plowing the fields. Since they couldn't make it, the crops will be less, resulting in larger agricultural prices and potentially even larger meat prices (animals have to be fed as well).
For the US: I won't lie: it could very well be a warning, yes. Trump can execute orders all day, but sick workers can't work, and if a significant percentage of a plant/factory/farm/whatever is sick, the output is halted. If this situational case happens on enough locations, there'll be a food shortage.
In any other country, I'd make the argument that flattening the curve is the solution, but America? Pfff...There's a part of the population that doesn't need to be told, and there's a part that's too stubborn to listen regardless. That latter part will protest for their right to work, the virus will continue to wreak havoc and you'll end up in the same situation as those developing countries.
...so on hindsight, I'll withdraw my point five. I considered it distasteful, but it may just as well be America's future.
