I'd disagree, once you get wealthy (and it doesn't even need to be that much), you can:

- schedule beauty appointments to fix how you look

- go on coaching sessions to increase your confidence and how you socialize

- take people out on dates without thinking "oh that's a bit expensive"

- buy dating coaches who understand the psychology behind dating and successful relationships

- buy therapists to heal your past traumas

Love is still not guaranteed, but you can do a lot to increase your odds.
