Eh, I reckon ghosting - romantic or otherwise - will be a thing for as long as people struggle to put what they think/want to say in the right words and leave it way way too long until it's really unbearably uncomfortable and it nags away in the back of your mind but you can't message them because it's been way too long and it'd just be really awkward. Not that I'd have any experience with that of course.

I don't think it's a capitalism thing as such. Having said that, I am really glad I got taken out of the dating scene a decade ago before stuff like Tinder etc. really picked up and you tended to meet people you wanted to date at parties or down the pub or through a friend. From what I've seen of it, it's so weirdly commercialized and the entire process seems to have become a bit like online shopping or job searching. Create a weird resume and hope that someone calls you for interview or some shit like that.
