I found your article very interesting! And I think the trends you mentioned could definitely happen. However based on my experience dating blue collar guys, the reasons women could choose blue-collar men may not often be true: (1) blue-collar men could be more likely to not have student loan debt however that doesn't prevent them from mismanaging money and having other forms of debt; also white collar men may have student loans but if they are making good money they can manage they loans; also this only relates to the US as other first world countries do not have as high costs for higher education (2) blue collar men tend to have more demanding schedules and usually have to work in person (3) their jobs definitely involve stress, some of those jobs require getting prepared or doing overtime work (for example, a plumber may need to examine or scope out a site so he could more easily complete the job with the designated time allotted) (4) true I'll give you that lol and (5) blue collar guys can be smart in their own way but tend to lack emotional intelligence (which is very important for a relationship to work)
