Why "radically different political interests," other than your obvious crass, transparent desire to race-bait?
Kids today don't care about skin color or sexual orientation.
They're far more global-minded. I'm in my 50s. When I was a kid a married couple would buy a home and live there until they died. Their children would in all probability live within 5 miles. Now people spend an average of 7 years at one address, and families aren't just scattered across the country, but over several continents.
They're more socially oriented, thanks to the internet. Most prefer peaceful solutions to problems and they despise bullying.
They're less reliant on organized religion.
Now this last thing comes from personal observation, but from what I've seen it looks like kids aren't anywhere near as materialistic as the rest of us. Sure they like having things, but the greed is good mentality from the 80s doesn't interest them.
