Do men avoid women who make more than them in a relationship?

Anonymous
My sisters a lawyer and her boyfriend is a forensic scientist, both good jobs but my sister makes more than him. She often gets people telling her her boyfriend is a simp for dating someone who makes more than him but I don’t see the issue? It’s not even a massive difference in salary where I live. Do men really avoid women who make more than them/shame those that do date women who make more? I think it’s stupid. Why does it matter so much? Why’s he considered a simp just because of that, it sounds dumb.
