Sure, but then you are also missing all the people who make below minimum wage because they are not formally employed. Which is a large number of people in Mexico. For example, the salaries of domestic workers are hardly ever reported (the average is around 2 minimum wages, but it is unclear what the lower bound is and is not like they work only 40 hours in practice, see: [1]), and the earnings of street food vendors probably vary a lot (it might often be above minimum, but in plenty of cases it could also be below).
