United States elections are by and large inherently for sale. One notable exception is City Council elections for Cambridge, Massachusetts – for the last 75 years they have been regularly fair, devoid of mudslinging and affordable for citizens of average wealth.
One solution to inherent evil is to walk across the street and set up your own inherently uncorruptible elections. Yes, it’s a huge amount of work and later on you’ll probably be attacked by the dictators-for-life. However, for the first few years you’ll be ignored. Figure out how to make your little neighborhood its own corruption-resistant democracy and the meme will spread everywhere.
