Rich buys when something is with good price low price poor buys just to spend money.
Middle class behave like poor too they buying expensive.
Simply put, poor people buy expensive things because they want to look cool, while rich people choose good things because of the demands of their work environment and business relations. The behavior of the poor people you are discussing does not reflect a good personality, they live in financial constraints, but still dress up with expensive items to look cool.
Prestige is like a fire that consumes dry wood, you will continue to be in poverty if you cannot manage your finances well. Poor people will remain poor even if they act like rich people, so there is no need to expect recognition from others if you still have debt or credit burdens.
