Besides Humana, I'm pessimistic mostly about people. I think global warming is frying the common sense and decency out of most of them.
But, it's hard to be sincerely pessimistic. I think Trump is a brainless idiot who's election to president will shore up leadership elections for years to come. I loved Obama and still do. But. I honestly believe he gave us all a false sense of security and led us down the path of complacency from which The Donald will eject us like bad fruit. It will probably take 8 years and I probably won't be alive to see it but I do believe it will happen and the country will come out better for it.
The older I get the more optimistic I get. Maybe because I can almost see my own expiration date. And I don't have progeny who's future I need to fret. So yeah I think things will get better, but if they don't, I won't be around for any I told you sos.
