Maybe.
A very short answer is that there are many differences between capital and labor. (It is even right there on the tin - we don't call our system "laborism", and a few actual words related to that meaning are popularly demonized in the U.S.)
Sure, sure, corporations are people ("my friend"), but most humans still see a difference between John calling in sick because he didn't like seeing his pal Bob fired and things like redlining, oligopoly partitioning, etc.
It has to do with power dynamics, and this is well recognized in law. (One example is that contracts between parties of disparate power are generally interpreted in the light most beneficial to the least powerful. For more extreme cases, look up the legal sense of the word "adhesion".)
And recall that capital always has options.
- Happy employees tend not to unionize. Many places normally considered to be natural homes for unions don't have them because management doesn't give them a reason to need one.
- If capital or management decides those proles are too uppity, it can close shop. (Labor also has this option, but that's called 'suicide' and considered in a rather different light.) Walmart did this a while back when (IIRC) their butchers successfully beat them and unionized; Walmart got out of the meat cutting business.
- Outsource. Amazon has a pile of circuit-breaker corporations that supply them backs and hands. Those corporations (really, binders on a Delaware shelf and bank accounts) take the heat from lawsuits when the backs break and the hands are smashed by robots. This use of non-human shields works surprisingly well in some circumstances, but the tight coupling with the mothership needed by app-driven job direction would make it look pretty strange if they set up shell companies to supply "workers", so that one may not work for Uber.
