[21:1] As he looked up, Jesus saw the rich putting their gifts into the temple treasury. [2] He also saw a poor widow put in two very small copper coins. [3] "I tell you the truth," he said, "this poor widow has put in more than all the others. [4] All these people gave their gifts out of their wealth; but she out of her poverty put in all she had to live on."
Ok firstly, this is talking about giving money to a homeless person (in its original context) secondly even if you have a good job, you don't always have half a bank worth of paper money on you plus some people in this world do have to go days or weeks with little or no available money, I have many times usually due to unforeseen circumstances.
Second, stop hanging around people that take all your money.
