The way my parents have explained to me is that they dont care if the guy makes $60K or $30K…as long as he doesnt lie. Financial struggle is also a part of marriage and as long as he is ambitious and educated, its alright. They dont care if your degree is in basket weaving as long as you are at least on your way to something. Ive never seen them specifically looking for well off families, always well educated ones. Honesty and being open is crucial otherwise it leads to mistrust.
Bank statements, sperm count, eyesight testing, etc is a bit much and Ive said this before too. I think basics like degrees, employment, residency and a background check that also covers references are a must though.
