The method i propose is to have communist communes of <100 people, who all go out to work in a capitalist society, and they then come back to the commune to split the money between all of them. There is no leader, as they would want more money, it is self-regulating. So, you could be a follower (commune) or a leader (capitalism). Either way, your quality of life is good.
Hospitals would be paid for by taking 5% of everyone's earnings in a tax. In a commune, it's 5% of the communal pot. For the capitalists, it's 5% of their own wages. This is then directly inputted into an NHS style health service, which is free for all citizens, but levies charges against non-citizens before they get treated. This will stop people coming over purely for healthcare and then leaving. There will be certain people who are exempt, but very few.
the police force would be minimal, existing only to solve crimes in the Capitalist areas, as the communes are self-regulating but effectively non-criminal within their own areas. However, if a communist is caught breaking the law in a capitalist area, they will be prosecuted, and the same works in reverse. If you do not work, you will be asked to leave the country as jobs will be generated for those who do not have them, and we will replace the weak with the strong. The military will be made up of recruited individuals, and funded by another 5% tax (see the above taxing method). This will leave us with a powerful military base, and all communes will be required to offer up at least 5 individuals if a war starts, to provide the extra manpower required.
In the communes, no-one will be forced to wear anything. The money you own is to be spent on what you see fit. This is yours, and yours alone. However, it is handed out of a central pot that comes from everyone's wages. So, your earnings are directed into a central account accessible only by an automated program that doles out the correct division of money per person per commune.
If you want anything clarifying, just ask. Now, my comrade, DEBATE!
