The US has a federal minimum wage of $7.25. Maybe some state has a lower minimum wage law, but if so it isn’t in force.
If I were making minimum wage I’d probably be more in the “buy an iPhone SE every 4 years” rather than “buy a top iPhone every 2 years” category.
But if I are going to critique other people’s spending patterns, I’d start with anyone who bought a new car, not a phone.
