My parents didn't pay allowance. My Dad said he'd decide case-by-case whether to give us money. I quickly learned the value of earning my own money.
I got my first job at 14, which later led to a very fulfilling career, in which I have made more money than I ever expected. It also allowed me help support my parents in retirement. (They're immigrants who never made much money, so I offered.)
My Dad came out well ahead by not paying allowance, lol. Mileage will vary, of course.
