"Poor" and "stupid" aren't helpful terms. The reality is we're heavily disorganized and stagnant, stuck in a scarcity mindset - leading the majority into lower level survival mode behaviour. Leaving it up to capitalism to advance innovation has been interesting, successful, however that doesn't specifically create leaders or organization necessary to solve holistic issues; it certainly has lead to creating pools of wealth especially as automation has occurred, and not being distributed well or fairly. This mess is quickly fixable with the right policies, leadership - educating the population to vote for that, while making sure elections are secure, are foundational supports of that happening; I hope for the world Andrew Yang wins US election, and that the FBI's warnings, along with Mitch McConnell's efforts to block measures securing elections, aren't realized into "Trump" being placed.
