We're already on the path toward blue collar salaries thanks to big pushes from government and big tech (Google,FB,etc.) to lower labor costs by inflating the supply of workers. You've heard it before - "not enough software developers!"... Yet salaries are barely moving? We didn't need it, but now startups like "Modern Labor" further incentives an ever growing influx of programmers into a market which is destined for over saturation.
Get ready folks. Your white color job, is turning blue faster than you even realize it. Find something to specialize in and do it fast.
