What makes you think a rich person is getting the same?
The fact that they’re almost certainly not using different apps for different users. And the fact that there’s no rich person tier for streaming services. They have no way or reason to distinguish between a rich person and an average Joe. It doesn’t matter how much money you have when there’s nothing to pay for.
Adding to what everyone else said, while GDP growth in one year doesn’t really matter much except if it’s really big or negative (i.e. shrinking economy) over time it can lead to big differences between different economies. No or little GDP growth is what we call a stagnant economy and for what that looks like in a first world country take a look at Japan. In short, though, it’s not a fun time.
