Say you’re born low class, bad parenting (abusive, absentee, whatever), you’re not especially physically attractive (you’re average), and you’re a less desirable ethnicity for dating in the western world. I think there are some hard limits you would run into.

I think it’s possible to raise your SMV and RMV, but not significantly.

Use the example of a poor minority raised by a single mother who is entirely average physically. Sure this person could do some self improvement, but he’ll hit hard limits where he won’t be able to increase his value.

I think that it’s necessary to be naturally exceptional in some way. Whether it’s looks or if you’re born wealthy or if you benefit from great parenting. You need something out of your control to go well for you and if you’ve got nothing then there’s realistically not much you can do to increase your value.
