The tragedy is that the blog post, and the resulting commentary here, are about identity, when the heart of the topic the author is _really_ talking about (if you actually RTFA) is class/capital. This tragic misdirection is the defining problem of our time.

The people who are working, be it white collar "tech" employee or manufacturing/service worker are those either who are forced to do so because they will starve if they don't, or, in our industry (and perhaps social/medial work), the monastic types who write Free Software (or similar) because it is the morally correct thing to do. To say that it's because they are white or young or male (or even that this kind or service is a privilege and not a moral imperative) is the kind of misguided, thinly-veiled class erasure that the predominant strain of big-C Capitalism is currently benefiting from.

Don't let people stereotype you. If you want improve your standing in the labour market, ORGANIZE, don't stereotype. Neoliberal capitalists are taking advantage of young people and poor people. Don't let them! If we play our cards right, they won't for much longer anyway! But please keep in mind that this kind of "ingroup/outgroup" mentality is a divisive thought pattern that deliberately works to their advantage! It has become common and tedious for a deliberate reason!

Your heart is in the right place. All workplaces mistreat you. Blame your bosses, not your co-workers!
