The in-line video link isn't working (for me). Anyhow, Reagan's a smooth-talker, but much of what he actually says is only relevant in the way that it's more of the same right-wing BS we're hearing lots of today.
He equates tax burden with oppression (complaining 33 or w/e cents/$ is killing america, lol - THE US IS STILL THERE 50 YEARS LATER), and states that economic freedom = freedom. Yes, that is indeed the case - FOR THE RICH. But not for everyone.
