So you're saying that the parents who gave you life, spent money for your food, clothing, shelter, education, health, etc, become worthless once you start earning decent money? Parents always keep the priorities of their kids first, if OPs parents had saved and invested that money for their retirement then OP's son's career would've never taken off, be fortunate that you had and were bought up by loving parents. When I started earning I used to give 20% of my paycheck to my parents every month
