In the 60’s Eastern LI was historically rural, with all that that connotes.
Not a Bad Thing, but much more in line with the fly-over country of the Times.
OTOH...even closer in towns, did NOT instill the same kind of "street smarts" and fighting spirit that are certainly evident in Trump now and which were bred into him.
Some of those who were born & raised in Manhattan, even into the highest social/economic strata got it; though with a bit more of an upper crust veneer than Trump has. That veneer began to peel away by the time the WAR BABIES came along and by the time the BOOMERS hit the scene, far more of it got scraped off.
