Do you mean https://ourworldindata.org/?
It would be far more constructive to give an actual link to proof than some massive site.
No offense, but that's like me saying, "You want proof that climate change is real? Check the internet," that's not proof, just some nebulous hand-waving. No one would or should believe that.
Their source data for the slight decline [1] in global inequality (which is only hypothetical) is the Worldbank [2], a source that has been heavily criticized for data-rigging [3-5].
The Worldbank also tries to present itself as helping to reduce inequality [6], so they have a bias for showing results.
I am not saying you are wrong or right, but let us keep the conversation quality on this website strong.
