Lots of guys and girls are avoiding the dating market entirely for many reasons.
In fact, the record keepers are showing that over 52% of the population in the US is single. Looking back into history, back in 1952 the single rate was only 15%. I avoided the dating market mainly because gender roles have significantly changed and men aren't viewed as they once were. Many people place their confidence level on their employment & income level, but they rarely realize this mainly comes from their mindset determined by proper healthcare.
It's not only because of changing gender roles
Reductionist science also has its' tentacles in the social sciences, even the dismal science of economics. They do not take into account that the healthcare system is based on reductionist science, therefore can't effectively prevent diseases, nor properly treat them without major side effects. This has a huge effect on the mental health of generations and has a catastrophic effect on the marriage rates, and thus the stability of the birth rate.
