Surrogacy. Rich couple looking for surrogate in poor rural places. Does anyone have an opinion on it?

Poor idea. Surrogacy is used just for women who cannot carry their own baby. Surrogacy is not for rich women's convenience. Surrogacy is costly, so wealth helps to afford a surrogate. I have met many surrogates and they are women who genuinely want to help and they go through extensive screening, medical and psychological. Surrogates make a big commitment, so poor women may not be a good choice. Complicated.
Can't judge. I imagine the couple is more interested in a healthy surrogate. It so happens that candidates in poorer areas may be more willing or interested in being a surrogate. If both parties benefit, i see no harm.
