Did you expect the business owner to brag about how much she's banking? Her customers and employees would love that. Maybe the article is accurate, but I don't

Did you expect the business owner to brag about how much she's banking? Her customers and employees would love that. Maybe the article is accurate, but I don't see any attempt to prove it. Each family spends 10% of income. Average household income is X. 3 teachers per 19 kids = Each teacher generates revenue of 0.63X. Considering each parent is making 0.5X in a two parent household, that's cutting it a bit close. Edit: I originally commented with an incorrect 6.3X. Fixed. 19 kids * 10% * X / 3 teachers = 0.63X
