At 23, you should now be able to teach your parents a lesson on being independent.
I think you're doing the right thing of saving up and then making them start a business or something that could generate income for them without you. While you're at it, start planning too on what you will need to do when the time comes that you will be giving them this fund. By then, you should be able to move out to let them be. Sakto na to imo pag.padako nila TS...
