Question: Did you make sacrifices so you could achieve these advantages? Or were you just given them because your local senator thought...hmm, DA is white, lets help him? That's the difference. Yes, some school districts are better than others. And your kids are advantaged by your life decisions. You chose to get a degree in something that can provide you a good enough income to take care of yourself. Should you be punished because others make different life choices and thus aren't as well off as you are? Should there be consequences for poor decisions? Should there be rewards for smart ones? I believe so in both cases. In many cases, the rewards aren't instantaneous either. But I do believe that I'm in the position I'm in today, simply due to the life choices I've made. Had I gotten a girl pregnant in high school, then my life would be different, I'd be much poorer and certainly not in the advantaged position I have today. But I wasn't lucky to not get a girl pregnant. It was a conscious decision. Other life decisions: I didn't go out drinking every Friday night in college (I was usually working). I worked all through school so as to keep my debt down. These conscious decisions are what give me my advantages I have today.
What you are proposing is basically telling people like me: "Thanks for skipping the fun and crazy parts of high school & college while making responsible adult decisions, but now I expect you to pay for those idiots who didn't."
