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.
When you are middle class in financial matters and you are in a country where all prices of goods, especially basic necessities, are cheap, then of course your monthly salary will also be appropriate, my friend, so I think the issue of reduced spending or not depends on how someone can manage their money, in the sense that for example by only buying various items that are needed without prioritizing desires that are not too important, unless you are rich.
On the other hand, I think one of the reasons why rich people spend much less money than middle class or poor people is because I think rich people know about the value of money, they learn from their own experiences when in the process of achieving wealth, or in simple terms they have extraordinary management of money and are able to use money properly so that they succeed in becoming rich, maybe poor people have not reached that mindset.
