You're leaving out children's programming on television. The first Spanish words I ever learned were on Sesame Street.
Keep in mind, the American school system also produced the Baby Boomer generation, who helped break down a number of racial and gender barriers. And that generation became parents and teachers (and also, unfortunately, Wall Street execs and Reagan voters).
Then go back a generation further and remember the great boom in organized labor, the jazz and blues lovers who brought African-American musicians to the forefront of popular culture, the Roosevelt coalition, and the New Deal. And those who fought against fascism abroad.
Every generation is susceptible to fear and prejudice, and every generation has voted in a right-wing congress at some point (Red Scare, the Gingrich era). But every generation makes progress as the world grows closer - socially, we have not turned back the clock.
On the other hand, every generation seems to reach an era of prosperity that causes them to try do away with regulation made in tougher financial times; and such laissez-faire fads generally end in yet another fiscal crisis. And every generation seems to find a new enemy to fear without and within (anarchists, communists, terrorists) - always posing a threat to our civil liberties and risking wars of choice (Spanish American War, Vietnam, Iraq) rather than necessity.
Bullshit. The whole problem is that people want two-sentence economic plans. They don't work, but Republicans offer them anyway. When people want economic plans they can understand, they vote for Republicans. When those naturally fail disasterously, they vote Democratic, whereupon Republicans take credit for everything the Democrats do for the economy.
