I think the subway cat could cope if she got a job.
I don't know anyone that would hire her.
In Nebraska, especially in Omaha and Lincoln, people like subway cat are those who run around with those orange vests picking up trash from the streets and sidewalks. It's part of their vocational rehabilitation--jail inmates, the mentally challenged, halfway house residents, whatnot.
Some resent it, but most come to like it. And they're paid for it too.
Actually, I think the biggest obstacle the subway cat would have, would be that she would HAVE to be at a certain place at a certain time on a regular basis. One gets the impression the subway cat lives a sort of anarchistic, chaotic life, and would find doing that harder than actually working.
But.....if the world the subway cat wishes to have, comes about, remember the old adage of Vladimir Lenin: "He who does not work does not eat."
Also, for the record, remember the subway cat is 42-43 years old. A lot of life wasted.
