No business cares about trying to reach people who don't have money to spend on their products. It's kind of common sense that FB isn't trying to reach 5 years old. Also, it's kind of common sense that Facebook doesn't have many people in China where it's banned. Out of the FAANGM's, the only one that competes with Facebook is Google and they aren't in China either.
But to be even more blunt. FB no more cares about people spending 35 cents online than Apple cares about people who only want to/can buy a phone that cost $100.
