Especially if they are from wealthier upper middle class type of areas?

I've noticed that latinas and asian girls who are 25 for example are more than open to going for older guys in their 30s and even 40s. On the other hand, I notice that white girls that are attractive and from wealthier areas seem to also marry very young (at latest their mid 20s) and rarely remain single for long after college. Now I am in my 30s but I am white as well and this is something I have been wondering about. I haven't met many older guys (of any race) that have had success with decent girls from that demographic.
