It's not the legal entity which represents your employer that tells you that you're part of a family to try and manipulate you into working for a lower salary. That's done by the hiring manager and your bosses because a) presumably the lie works often enough that it's still worth using, and b) because they are paid a little bit more when they can get away with paying you a little bit less.
It's also one or more people who decide that despite being a loyal, hard-working employee for X years that it's time to let you go so you can be replaced by a fresh grad, an overseas hire, or simply to close your position to pad the yearly bonuses of those higher up the chain.
The entire concept of a corporation is to act as a shield for blame to prevent any landing on the individuals within - don't fall into that trap. Every decision made by a business, no matter how amoral, immoral, or even illegal it is, was ultimately made by people.
