First of all there must not be poor that is not some universal law. That is based on scarcity in a human's mind. Wealth gap has not widened. Your mistake is that you hasn't taken into the account that the world population is still growing mega fast. More people are coming in faster. That means it gives the impression that we have more poor but we have not. Everyone across the board is richer than their grandfathers.

There is no such thing as equality you are correct on that one. But that is the beauty of humanity how we are all different in our capability. That you can take it into your own hands and empower yourself that is the beauty. Human history hasn't had this explosion of abundance as we seen the last 500 years. Perhaps once they had but not as far as we know. So look at the past may not be a good model.
