This. Wealth becomes a great divide especially when you become parents yourself.
It’s really based on how your parents set up your relationship when you were young. DH and his siblings are all very close. Sometimes sisters disagree, but not feud level.
My parents were competitive with themselves v. Peers and that bled into sibling dynamics. “Larla got an A. Layla only got a B.” “Layla came in first in the race. Larla, you need to work harder.” who came in 5th.” Our relationship as siblings tanked in our later 20s. We still get oddly competitive when we see each other. We are both pretty normal in our regular life.
