We don't just work more, we spend rest hours that we are not working think about the work. In short, we never stop working.

What do you mean by that? Like in the industrial / manufacturing age where people manually did the same thing over and over? Where people were physically exhausted but not mentally?

It probably was, except that there weren't blog posts about it.

Depends on which people you talk about and during what period. In the grand scheme of things, renting out most of your waking hours to an employer who charges you for that service is an extremely uncommon thing to do.
