Capitalism is the best economic system we’ve ever invented.

If you limit yourself to only seeing the first-world and not the exploited third-world countries that produce the majority of our goods and provide us with resources, sure if you ignore first-world class-based inequality.

Guess we also ignore that e.g. your cell phone was made in part with child slavery (unless you bought a product like the Fairphone). Out of sight, out of mind - am I right?

Democracy is the best political system we’ve ever invented.

Even in the best case scenarios, we’re still exploring how to implement democracy and have it actually reflect the spirit of the concept. Representative democracy in its current iterations is truly a farce and is far too corruptible. Increasing levels of direct democracy or decentralized governance would likely be desirable. Having the most-qualified experts empowered to solve our problems would be desirable, as well.

Problem being, both need serious guard rails.

Democracy needs less guard rails and capitalism needs more - if we can continue to justify its existence as the dominant economic system.

The electorate has to be educated as to systems and morals.

Indoctrinated would be a better way to put it. Indoctrinated that capitalism is the best system ever (so don’t hope for a system where people aren’t fundamentally exploited), indoctrinated to unquestionably accept fundamentally broken systems (and allow ourselves to be dominated by hierarchy), and identify with state-proscribed morals. Sounds like an amazingly free society that you are advocating for.

People are far less stupid than you let on - we need open and fair discourse, we need to ensure fair media, we need to cut out partisan tribalism, and we need to stop acting like anything we’re currently experiencing is desirable or even close to being “the best”.
