They end up on unemployment till it runs out. Then if Walmart will hire them or maybe Lowes, they MIGHT find a job.
Lately though, Walmart has downsized their Sam’s Club staff.
The pay is not great, but at least Walmart is one of the very few places that does not discriminate against older workers.
And if they don’t find something at Lowe’s or Walmart, do they usually end up on welfare or disability or do they end up homeless and dying of starvation and lack of water? Which is more likely, if they are not married and presuming no other family support, which again is fairly standard for those over 50.
