No, if you were a lawyer making 250k a year for two decades then came to court saying you “just took a job a footlockers last week” and asked them to use your minimum wage salary as the basis to calculate child support you’d either get laughed out of the court room or the judge would ask you to spread your cheeks because you’re about to get raped. Lol if what you’re suggesting is true that’s what everyone would do and you’d never hear of wealthy people paying thousands in child support
