Then the downside is lower paying jobs if there isnt corporate.Your point about Florida white guys seems valid. People in the Northeast are more serious minded as compared to people in Florida. I imagine the white dating scene in Georgia is not good at all. Social circle would be quite important there post college and even in college for those who attend college.
There is some overlap between the concepts of ratios and competition. Almost every US metro has an oversupply of males problem under age 40-45. While there is an oversupply of males in San Fran/Bay Area, most of the oversupply of males are males with poor social skills, tech guys, etc. In Miami, there is also an oversupply of males (though less drastic than San Fran from what I understand), but the typical male has better social skills. The type of male that lives in Miami is more socially skilled. Miami doesn't have the corporate jobs that San Fran has. Areas with big time corporate jobs bring in a lot of boring males (this community would call them AFCs/betas) because most white collar workers are boring, bland males, even the non-technical roles.
