Socialism and You

So my eldest brother, as my eldest brother will do, posted a pro-union screed on Facebook about the Verizon strikers winning the strike because Verizon didn't force givebacks.
My brother has what we might euphemistically call "conservative" friends.
The first response on the Facebook thread was:

Contribute to your health benefits like all the rest of us do. Why should you be any different?

Why indeed?
What's fascinating to me is that essentially this argument is communistic. Why should one set of workers be any different than another set? We should all be the same, comerade.
Now, I'm sure the writer consciously believes in "free markets" and hates unions and otherwise despises all things that are Left-ish or Liberal-ish.
But he also wonders why some workers should be any different than others.
Why? This isn't any kind of Marxist communism, this is just down-home, 1863-style (heck, maybe even 1789-style) communism.
Of course, the Lefty answer to "why should you be any different?" is "Well, because we used collective bargaining we didn't push for higher pay, but rather health care, and because the employer gets better tax breaks for providing health care, that's what they agreed to. We'd like them to hold to that agreement."
So... that's a thing.

Why should those Verizon workers be any different?
Maybe all workers should be paid the same. Hmm...
