Yes the minimum wages are a joke. BUT: Very few citizens will work for those wages. However depending on what state you live in many citizens work for as little as $100 to $150 pesos a day. Converting to USD is meaningless as workers buy their items in Pesos. On top of the meager wage a worker is supposed to get Seguro. Paid by the employer. This includes: Pension, Health Insurance, Worker's Comp. and unemployment insurance. Many low age earners do not get that coverage. An illegal practice. Workers in Maquiladoras usually get the minimum wage. I am not up to date on their wages but Auto plant workers make around $1500 pesos a week to start.
