Can't say much about the gap between the rich and the poor and it's size, I believe that it's all relative. The one thing I'm certain of is that the advances in modern technology make it much more easier to make a profit even when your skills are rather lacking or you don't have the necessary education for a high paying job. We have all the tools that can help us make a considerable amount of money available to us in our smartphones, laptops, etc. The single most powerfull tool, in my opinion, is AI. Lets take AI generated cat videos for example, most people have seen them, some are even addicted to them. Just a few years ago to make such a video and make it profitable, the creator would have to be a decent animator, or a cartoonist, these days you just enter a prompt hit the "generate" button and voila a cat bartender on a cruise ship serving drinks.
