For those things you're talking about my parents paid their fair share of taxes, not me. You have to realize, it's parents who pay for their children's education and healthcare, not children themselves: this is true whether we're talking about public or private.
But even if you were right and indeed it is me who is supposed to be paying taxes now for my education in the past, then this sounds a lot like this:
- Here, have a free sandwich
- Ok, thanks
- You ate it? Now give me $10.
Oh wait, you needed the State then. Now it just seems inconvenient to you.
