It’s not, if you want an educated population that is productive and then pays for your DINK friends when they are old and decrepit. Our kids will pay far more taxes and will contribute far more to society, than your childless friends. I’ve got four future earners I’m contributing to the betterment and future of Canada. If your friends opt out, then I guess I get to too. Right? By your reasoning, my kids won’t contribute to their healthcare right?
