1. Men that get casual sex aren't "alphas", often they just don't meet the extra requirements for a relationship.

  2. Men that get casual sex may be more attractive but that is about it in terms of what features they have that are "better".

  3. Women work so men aren't supporting them, this isn't the early 1900s where men would have to wait for marriage for sex and support the woman.

  4. Men that have casual sex don't get to pass their genes on. In terms of the term "alpha" in the wild, the alpha gets to pass the genes on not usually betas. But in casual sex condoms are used and if the woman gets pregnant she usually has an abortion. The one that gets to pass their genes on is men in ltr.

  5. Guys in ltr don't have to "put in more work to get sex", ltr and dating just works differently than hookups and if what you care about is sex and you are jealous then just try to get a hookup not a relationship.
