Millennials were born centered around 1990. Most of them were in their late teens by the time social media as we know it today really entered the zeitgeist. Even if it's true that social media is distracting in a way that affects education and skill development, this would have an impact on younger generations, not as much millennials, who are used to the internet as a tool, not as an integral part of the world.

As for the premise itself, I find it doubtful. All of my friends below age 30 (i.e. past millennials) have a much stronger working knowledge of marketable skills than I did at a younger age, as well as more open and free resources to develop them. It is most often access and connections that block their career progress, not capability.
