I want to ask my son for his wages in the future.
Why are you asking for money from him?
He won't be able to use money. And this is a good opportunity for him to learn how to save
Your son will use his money and your motives for teaching him how to save will only end up teaching him not to trust you. Its up to you to earn your own money and so you shouldn't expect money from your son. Your son needs this money to save for his future.
Why are you trying to ruin my life?
I am not trying to ruin your life. It's just that it is your responsibility to earn and save your own money, just as you would expect your son to be responsible for making his own way in the world.
