A good example of this is the current tax debate. Republicans claim lowering taxes is a great way to "jump-start" the economy. But if you look at Kansas, a state that has been running that experiment for half a decade, you realize that it's a terrible idea.

But then there are other states, like Florida IIRC, who have also been running that experiment and succeeding. So then the key is to see why one works and the other doesn't.
As an individual it seems great to go work there as opposed to here in CA because there is no state income tax, yet I still make way more money here in CA because there is practically no industry in FL unless you're a lawyer or a doctor.
Succeeding by what measure?

The one tool we can wield in this information or rather misinformation age is critical thinking. I no longer follow any pundit. I have nowhere near their knowledge in their respective fields, but I can think and ponder whether their views make sense. Robert Reich, Krugman, Brooks, Shields, Shapiro or whomever. See what slant they are coming from, try to understand if they make sense. Immediately afterwards, read about the same topic from someone on the opposite side of the spectrum. Don't get lost in the doomsday world is ending, other side is evil BS. Then hold an opinion, but don't stick to it. Allow it to be malleable and change and try arguing from the other side constantly. I feel like our own ego is partly what let's us join each tribe of thought and we further reinforce it from reading similar viewpoints because we want to be good and right. Sounds simple, but it's so easy to get caught up in it without taking a step back and just thinking about that thought process.
So, that's how you keep democracy alive. Not through simple education where you reiterate facts, memorize or follow directions, but through improving critical thinking which is slowly worsening in college and high schools. In a conversation with a classmate, we reminisced how in 3rd grade we learned how to spot bias in news articles, practicing for months. I feel like that's disappeared too.
