Being poor doesn't really mean that you should be a beggar. If you have difficulties providing your needs and your salary or income is below than what is usual, you can be considered poor. It isn't really something to argue about. It is clear to see the difference between the rich and the poor. The rich ones who suffered a lot about money doesn't mean they are actually poor, it is just a matter of a choice for them to spend their money wisely or not.
I think being poor is subjective term depending on the person. If you are a minimum wage worker in some third world country making less than 1 dollar per hour and need to take care of your family with that money that's a global way of saying you are poor. However if you used to be a millionaire and now you bankrupted and still have a house and need to go to work and make a decent salary that's "poor" for your old standards.
Poor can be different in everyone's situation, for example I feel like I am much more poorer than I used to be, when bitcoin was going up I was living luxurious but now I need to work hard to pay the bills but that "poor" I feel is nowhere near the minimum wage worker with 2 kids so its subjective.
