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.
