What are you saying ? That owning rowhouses in the city promotes more of an understanding of private property than an acre in the suburbs ?
I'll bite - how do suburban homes differ from city homes in their private property aspects ?
Let's see - people in cities pay property taxes, wage taxes, city taxes, and usually extra sales taxes, while people in the suburbs pay property taxes, township taxes, and that's it.
I think you have your statement backwards.
The underlying economic principle of "private property" is that it gives the owner/occupant a true stake in developing something, creating something, building something, selling something, etc. . . . and that this has always provided the best climate for long-term growth and stability.
Someone who lives on a working farm, lives upstairs from a retail store, or runs a business out of his/her basement is truly a "private property owner" in every sense of the word.
Someone who lives in a suburban home and works in a city 10 miles away may have his/her name on a property title, but the reality is that in the larger economic context, this suburb is not all that much different than an apartment complex or a company-owned town.
