>Does the democratic economy you describe exclude private property rights? How do you seek to build it?
There would be no private property, but there would, of course, be personal property. I'm not opposed to individual ownership of land or housing or whatever so long as the owner is the only one who depends on it.
>How do you seek to build it?
That is something I haven't quite figured out. I have tried to move past the reform-or-revolution paradigm, and instead focus on whatever methods are available to build a democratic economy. They can include things like labor organizing, tenant organizing, paramilitaries, and electoral activity. One thing I've thought is that organizations that plan to bring about socialism should be structured to resemble the socialist institutions they seek to bring about. For example, labor unions should be structured to resemble the sort of democratic workplace that its members seek to create. The goal would then be for the unions to eventually build up enough to power to kick out the bosses and take over their workplaces. I believe that was what the National Confederation of Labor (CNT) did during the 1936 Spanish Revolution. I suspect the CNT could be a good model for other unions to follow. I would advocate a similar approach for tenants that I advocate for wage laborers, but taking over rental properties rather than workplaces.
I think labor unions have a big role to play influencing electoral politics too. For example, if a government is unwilling to enact a policy that is popular among the working class (like Medicare for All in the U.S.), unions can conduct a general strike to ensure that the government does what it wants. Bear in mind that capitalists use capital strikes to protest policies they don't like, so the working class would basically be copying a common tactic they use.
