Any reasons a man gives for not getting the caliber of woman he wants is a weak excuse. It's p*ssy. An adult male human brain is capable of seemingly anything it puts it's mind to. We live in a world where the Hubble Ultra-Deep Field is an actual thing. Any mentally capable man complaining about not getting p*ssy because of girls feeling big headed from social media thirst is disappointed with themselves, not 'this generation'.
Social media thirst is not making these women anymore confident than they would be otherwise because it's not actual real-life self-esteem; it's narcissism fed by fake validation from others and worse, strangers. Actual unbreakable confidence is rare in young people (regardless of gender) because most of them haven't succeeded enough on their own in ways they could measure, so these girls typically use men on social media they know are hard up on p*ssy as a substitute for legitimate positive reassurance. Most of these women rely on it like a fiend relies on heroin; it doesn't put them on cloud 9 after a certain point but the lack of it makes them sick. They've developed a tolerance and a dependency on it.
That means today's women aren't really as big headed as they seem. They may even have low self-esteem since now they compare themselves to other women in ways that can actually be numerically measured; likes, followers. When the next chick got 20,000 followers, you're 10,000 ain't shyt.
The idea of dudes not getting p*ssy for any reason, much less the internet, is laughable. Those girls you say are gassed up are getting fukked by somebody. Period.
