Because its not about dominating, its about agreeability. And like someone said here, its not a one or another thing, but a spectrum.

In reference to your example~ There's a big deception about alpha and beta. People think that being dominating and powerful means that you are "alpha" or less feminine. But in reality, In the example you provided; what if the man decided to say fuck you, as well as tell you off and quit the job himself? Wouldn't that make him just as, if not more alpha as the one who took his position? Likewise, is the person who is taking all those orders from a higherup actually the alpha when it comes to his boss?

That proves that its not always about being a bad person, or morally incorrect, or powerful. That's not a deciding factor on whether someone is alpha or not. You see this example with lots of rich guys, or people with phds, or celebrities that for the life of them cant stop being beta. They may even have lots of female attention and attraction at first glance, but this is also not even a deciding factor on if someone is alpha.

"""""I don’t get how you can be happy and want to serve someone who acts selfishly and puts themselves above you with disregard for you."""""

1. Not only subjective, but this thinking is limited to the trends of the world we live in today, and not a representation of the total. For example, this cannot be said about the old righteous kings of past who for example, managed kingdoms with selflessness and attention for its inhabitants. They were still desired as idols and examples of men, and alpha while still being caring etc. And I'm using a king as an example. Because in the world we live in, the model template of 'alpha' you speak of, is simply only in todays time the morally and socially agreed upon model of "alpha". We should also consider the times where cultures were different, and when perhaps piousness, virtues, moral precision were seen as a alpha trait- Instead of like how today; sexual immorality, mental manipulation, and wickedness may be seen as such. Agreeability is once again key to understanding the feminine dynamic. Also remember some things are bigger than both masculine and feminine (righteousness for one example), thus why a person is on a spectrum.

"""""I don’t get how girls want someone to take control and be like I want to watch this and we are watching it. I want to listen to this so we are listening to this. I wouldn’t want to be a partner to someone like this I’d be like fuck you. I’d want my desires accommodated. Why do girls want to act a dog to a guy."""""

1. Its the difference between wanting to be the CEO and head of lamborghini (someone elses stuff), vs wanting to create your own car brand named something like "Coloradoci". Servant vs Master. Her wanting to be part of your own story of consciousness more than wanting to be part of her own story. Agreement of your role of being the powerful(dominant) vessel and hers as the lesser(subservient).

"""""I don’t get why anyone would ever even talk to the alpha. I would only want to do favors for someone who does it for me too. I wouldn’t want to serve or help someone who is only concerned about themselves wtf.""""""

1. You would think like that, but someone who is agreeable would not. Whether a woman is scared to lose you for whatever reason, or because of the sex, or because of the title, they are benefits of being subservient. You say that you would only want to do a favor to someone who does it for you, but if someone were to apply for a fast food job, did the taco bell or McDonalds first have to save their family? Does the worker not make the company way more money for the company and CEO than themselve? But the person at the end of the day accepts that he is not the CEO, and at the end of the day is in a agreement not to destroy the chain or create his own fast food chain, but to do what is told to put food on his table. It doesn't always have to be such a sad situation....but at the end of the say its pros and cons with a agreement from both party's. Because trust me, if a woman saw no value in you she wont stay with you. Just look at the crazy and homeless. Even if its just to hold the title of fiancé or boyfriend, or for social signals, or "alpha fux", or to be in a companionship with someone who will fight for them, or to be part of a more morally precise/honor-ous persons. The same way someone may want to be the side character in another persons movie. If the movie was some lame box film you wont want to be.... But if the movie was batman you may think twice about being robin. It all goes back to the virtues/desires/VALUES/etc. of the person willing to take the side role, and the benefits or Pros.
