Angry white geezers

Today, one of Ned's valued associates mentioned in passing that 'a lot of old white men are angry.'
Ned nodded and went on with his business, but after a bit stopped, said "'alf a mo!" and wondered just why , if indeed true, this is.
Aren't most of these angry old white men retired on social security and Medicare? And isn't Medicare free for Part A and only a hundred bucks a month for Part B? Haven't a lot of them also managed to get certified as 'disabled', as 18 million people have, thus qualifying for still more sucks at the Great Public Teat?
Don't a lot of them also get defined pensions from some government or business? Don't many of them get military pensions as well? Don't at least some of them have working spouses?
In other words, WHAT THE **** DO THEY HAVE TO BE MAD ABOUT?
Now, if they are under 62 and out of a job, well, yes, they have a right to be MAD AS HELL, because Ned knows all too well how difficult it is for anyone over 50, male or female, who isn't a member of the sneering plutocracy to get work. But it appears to Ned that the people who are the angriest, those at "Tea Party" rallies, for example, are also those who are obviously eligible for all the goodies that this society showers on anyone over 65.
So Ned wonders again why they are so angry. Are they afraid of "socialism?" The "socialism" that is represented by their essentially free health care and social security? Their discounts every place in town because they're over 60? Their free or cheap bus rides? Their ability to call a bus or car in many localities like Ned's and be chauffeured anyplace in town for peanuts?
Or are they just mad because a black man is in the White House?
