There are, in Mexico, 3,277 people employed by the federal government who earn more than 2 million pesos a year. That is well over $100K USD a year. This might not sound like that much in the U.S., but, for comparison, a teacher makes $7,812 USD in average for the whole year in Mexico, and someone making minimum wage would get $1,400 USD or so. We also have the fifth most expensive legislating body in the world.

In the absence of any negative repercussion for being caught, and in a culture that normalizes corruption, higher salaries don't make the majority of these people non-corrupt.

Economic inequality is both a cause and an effect of corruption. But it is not true that high wages for public servants are a vaccine against corruption.
