Sorry, I am going to be the insensitive sleazeball here.
The point of staying at home is not that if you get this disease you are going to die. The issue is that if we ALL get it then a larger proportion of people are going to die because we don't have enough hospitals.
We had to choose some people as being important enough that they are allowed to be out and about and use some of that valuable limited healthcare resources while the rest of us try really hard not to get sick and risk going to the hospital. If this goes south, you may wish that you were one of the people who got the disease early.
Farm labor has always gotten the short end of the stick and this is an added burden. I would vote to give them extra income during this period if that was being considered. But the fact is that they are part of the food chain in this country and so are considered "essential" people to continue doing their jobs.
