Haha, I see a lot of changes here. As far as I can tell by myself, I am a child of a middle class family. That's why I spend money thoughtfully. But it depends as much as to say what kind of state he lives in and what the price of everything can be. Let's say you live in a country where everything is very cheap. Your expenses will decrease a lot but you spend based on your mindset. Like I always spend a little more because I like to spend money and I'm not a spender.
So many times it is seen that a rich person spends very less and a middle class person spends a lot because he has a high spending mindset.
