That's because men primarily need women for sex and not that much else.Your personal feelings mean nothing against hard facts. Single women do much better in life than single men. They are healthier, live much longer, happier, and are more content with their social circle than men. Several studies report this and I posted a couple in the OP.
Presenting your perspective as facts doesn’t make it true.
I would agree with you if it were maybe 50 years ago, but single women of today are by and large choosing to be. They see men as burdens, which is unfortunate. But again, the studies support this.
And you don’t see women buying sex and companionship at the rates men do at all.
Women need more emotional support which they can probably get from other family members and kids etc..
I hear your points though and I see the studies... but unless they are sticking electrodes on their brains and measuring their happiness the women could just be lying for the study about being happier. Lies, damn lies and statistics. You should take studies with a pinch of salt. What locations did they target? how large was the sample size? where there demand characteristics at play? I.e. where the women deep down knew what the study was for and hence complied.
Not arguing a lot of women are happier being single now though. I think its more of a generational thing and we are just a more individualised society as a whole. Whether that's in our best interests time will tell.
Edit: Seeing a lot of my points have already been mentioned
