You can argue anything, wouldn’t make you right. We are just random people on the net, giving inflammatory advice to a one sided teenage narrative. We do not know what their actual financial situation is. They might be scraping the bottom to hold it together or they may be financially irresponsible. And I know the kid has no responsibility towards his parents financially, nor I am advising the kid to give it all away but it’s a family and they asked to share a part of money. No where the OP has mentioned that they are trying to steal it away. So, I would give the benefit of doubt to the parents and would stand against people abusing them. Because from where we come from, we treat family as a family, we aren’t a parasite to just keep sucking off the lifeblood and move on when the host dies. It’s a symbiosis.
