> Why are supposing that all rich people made their money through online advertising
If you replace "all" with "most," which is how I phrased it, then your sentence sounds like this:
> Why are supposing that most rich people made their money through online advertising
Ok now we're onto something interesting, but I can see how you might be still struggling with the phrasing. May I suggest to reformulate as follows:
> Why are supposing that most rich people made their money by selling something for more than they paid for it?
Perfect! So we just have to answer if in the context of most people who became rich, "online advertising" = "selling something for more than they paid for it." I would argue that you can sell things without advertising them, but you certainly have to make people aware that you're selling those things one way or another (and mind you, in the context of rich people, you have to do that at a very large scale). So when answering how MOST rich people attracted attention in 2021, and that AT SCALE, I think the above is not so untrue (you will certainly find many who ALSO used TV and other channels, but very few people with a TV budget had a $0 paid social budget).
