- I think Shenzhen is a good model of a an SEZ providing benefits to a local population. Hong Kong and Singapore also demonstrate how city states can rapidly grow even when the local population is relatively uneducated and poor. Of course there will be wage differentials based on productivity, but in the long run those differentials are best reduced through inclusion.
- If the proprietary city is in a country that was previously part of the Commonwealth, the proprietor could designate the Privy Council as the highest court in the land. Singapore, for example, did this for the first few decades of their independence. More generally, the proprietor would have a strong incentive to promote fairness in the judicial system. There is a great deal of academic literature on private dispute resolution which suggests it is typically unbiased.
