People make life choices based on how things are, not how they ought to be.

Generally a “gold digger” refers to a young woman who marries an elderly rich man with the intent of gaining a large inheritance, not a young woman who marries an established (but still working) man a few decades her senior with the intent of raising a family. A big “gold digger tell” is that the rich guy already has adult children who end up in a feud with his new young wife (because she represents a threat to their inheritance).

Some men love gold diggers my uncle is one such man. In his own words "gold digger are the easiest lay".

It's fucked beyond measure
