I said none of those things and I won't explain what's already written in front of you (talk about understanding context). Just keep in mind that excess of labor force in a sector leads to decrease in wages and increasing demand in neglected markets. Between 'we demand jobs for philosophers' and 'everybody should just study IT' there are more balanced scenarios. Trends don't change in one year cycles - when you notice that something went wrong it's already too late and it takes long years to fill the gap, and only assuming a too agressive correction doesn't happen.
