Green Day - Working Class Hero Lyrics Meaning

It has been really interesting reading all the interpretations of the lyrics to this song. Wow! One thing that's really cool is that the song gets people thinking. I guess a good song/poem is like a good piece of visual art--people spend time thinking about it, discussing it, and enjoying it. Okay, now for my humble interpretation...for me...at the beginning, I picture a typical middle class family putting a toddler in day care (or being put in front of the TV/Computer anything that gets that child out of the parents' hair--"giving you no time instead of it all")...then at day care/preschool/kindergarten, the child learns that he/she is just one of the other kids--not special or anything...just walk in a straight line, follow the leader, just blend in with everyone else.....don't try to be special or be too smart or too clever.....then it continues in elementary school. You've got your standardized tests that you have to take twice a year (and much of the year is spent training to take these tests--learn to fill in the bubbles, etc.)....just be like everyone else....don't be different or the other kids will make fun of you, and the teachers won't know what to do with you if you're too smart or too slow. Just be the standardized child.......be a middle class student---not too intelligent, not too dumb, not too perfect, don't cause any problems and you will be a "hero" to other people in your school. Then throughout middle school, high school, and possibly college, the cycle continues.....just blend in and you'll be okay. Then when you graduate from all of your schooling in learning how to function in mediocrity, now it's time to find a mediocre job/career and continue to blend in and keep trying to keep up with the Joneses. I always took it that Lennon meant "the working class hero is something to be" facetiously...Anyway, I don't know if this makes sense, but this is what this piece of art says to me--just conform and blend in and to the world, you will be a "working class hero."
