It's not about age. Compare Sanders and Trump; their politics aside, just take being able to hold a conversation and have honest arguments, listen to advisors when they really are right, that sort of thing. Or Mamdami and Thiel. And hey, I'm sure there's some young-ish, bright, yet very capitalistic people who also have a good head on their shoulders, too. I just really like Mamdami, partly because how even the Dems shirked him before he won, and then Trump was like "I like that guy". He probably also likes Thiel. Which shows anybody can do anything, it's totally... random! :D
