A few examples of things we could do to stop a little the bleeding out of democracies:

1. Outlaw lobbying;

2. Tax the ass off the filthy rich;

3. Break up big corporations in tech, oil, media, you name it. No more monopolies or monopsonies;

4. Change the electorate system.

5. Increase work conditions. Higher wages, jobs availability, social welfare, etc.

The obvious takeaway is that if you reduce wealth inequality you get a healthier society and democracy.
