...nah, SLR is like a massive food hall with five-star restaurants and MacDonalds, and a variety of other eateries. They even run their own dinner. So in that regard, cams are just more variety.
You're completely right about the addictive combination of the tipping culture and sex work. Before we had cam girls, men would go down strip clubs, and blow every penny they had on some girl they'd fallen in love with, and they'd always be back, night after night. Sex meets late stage capitalism, throw in the pervasive reach of social media, and now you're literally strip mining entire demographics for cash, and making a lot of men poor. Seen it happen to a friend of mine.
But it makes bank. It makes more bank in porn than anything else, so yeah, it ain't going anywhere. May as well pull up a chair, i have plenty of popcorn...
