Instead of extending these advantages to young people, they sold them down the river to an actor pretending to be a conservative, who got off on police shooting protestors and buddied up with apartheid South Africa. Why? So they could get pay less taxes and get false promises of "animal spirits" inflating their 401ks. And when the social progress they ostensibly fought so hard for came up against the wall, they chose to let schools be resegregated, throw all the POC drug users in jail, and have LGBTQ people die of AIDS (because, y'know, property values).
This disgusting rightward lurch sets the stage for a CIA scion to pretend he was a cowboy and kill half a million innocent people in the Middle East and destroy the economy. And now a parody of Reagan himself to do the same or worse, putting the nail in the coffin of Millennial's future.
And also: Ended the Cold War? Look at 2017 and think about that one. More like destroyed an already poor country with corrupt Capitalism, so the KGB could take over and come back at us even stronger.
