We must be careful about money, if you are careful about money then there is no problem if people call you stingy because some people's job is to say bad things about others.
If you are frugal, you don't care what others say. As you learn to be frugal you will surely learn to improve your situation. If you don't listen to the negative words of people in the society and change yourself, you will never be able to improve your situation. Money is the most precious thing to spend your life. So money is definitely needed in every aspect of life. If you can use money properly then you can definitely establish yourself.
No matter how rich you are, you need to be careful with your money because there may be times of danger. Nowadays everyone earns money but very few people care about their earned money. Because people spend their earned money in various bad ways due to which it is seen that they spend more than what they earn.
So we should be careful with our money and even keep it as savings for future so that in case of danger we can use that money and get out of our danger.
Kind of mentality where it's easy to spend their earned money comapred with saving it to make sure that they've got something if ever emergency things happen, I agree with your statement that most of those people who are earning money are more on spending it after they've recieved their earnings, not realizing that not every time you'll gonna earn, and what if you lose your source of income what will happen to you? kind of things that you need to prepare yourself, saving and investing will be the best option to make sure that you save something for your future.
