Nonsense. In the real world people don't just buy a house because of their taste. Budget, proximity to family and friends, transport, schools, bedroom space, work from home space, etc all factor in.
Not everyone has the time or inclination to spend huge amounts of time 'styling' their house. Just like people from all class background have different levels of interest in fashion, makeup etc.
Some people are just so desperate to be 'better' than others it's embarrassing. And definitely not a trait I would associate with some who has generations of wealth and 'class' behind them.
