It is not right to say more STEM means wages will be lower. In high end professions like engineering etc. more people could mean faster innovation and faster expansion of the industry.

For example despite relatively higher number of tech employees Silicon valley engineers earn lot more than engineers pretty much everywhere else.

Even if there is a relative drop in wages, everyone wins because lower wages eventually drive the prices of services provided by these people. For example if Google's salary expenditure reduces it might also reduce advertising prices almost everyone else.
