In prehistoric times things were quite simple because “power” was derived from immediate personal traits of a man: physical strength, agility, intelligence, confidence, etc. If he had these, he obviously also had the signs of these which women grown accustomed to: confident body language, a muscular build, etc.
Nowadays “power” have a different meaning: money, connections, whatever. But women’s instincts are slow to change so they are still attracted to the “old” signs of power. This is the source of misunderstandings, because people perceive politicians, doctors and lawyers as alpha because they have power, and then keep on insisting that the alpha-beta distinction doesn’t work because women are often clearly not attracted to these “alpha” men, instead they desire thugs who are considered betas (or worse) socially. But women are still attracted to men they were attracted to for millions of years, it’s only what we socially consider alpha has changed.
So, if you want to get laid don’t (just) concentrate on acquiring alpha status socially; you should focus on what women desire.
