If your parents were invalids or dying, then I would say helping them and loving them would be the right thing to do. (Mark you - they wd dump you in a flash if the borg told them to)
They are both young enough and have skills to support themselves if they get up off thier ass and and get cracking.
As it is, if you give them what they seem to expect they will not appreciate you. They will just say "Jehovah provides" and no gratitude or acknowledgement of your kindness.
Dubs EXPECT other to give give give, whilst they take take take.
