It would create more stuff by increasing market size. Those poor would be able to afford more stuff, so more stuff would be made. I'm currently in process of making something people don't need, but might like (recreating old glass who everyone remembers from their youth). I can't produce too much, because it's not competitive with cheapest glasses. If more people had more money, more people would be able to impulse buy that glass and I could make more of it. If more people had money, they would be able to do such things themselves, I'm only doing it because I'm earning a lot and banks essentially compete in who can give me the cheapest money to do interesting things. It's pretty funny actually and I have access to money much more cheaply than poor people (lower interest rate).
