I have confused "property" with "wealth". Apologies.
It is wealth rather than property which is primarily created. The amount of physical property in the world changes only very slowly, while the amount of wealth grows rapidly, due to people finding better and cleverer ways of rearranging their property in more useful ways for themselves and (mainly) for others.
I don't buy this at all. Bill gates is a great businessman, but there's nothing created by Microsoft that was not done better, cheaper, and earlier by someone else.
I should have picked a better, less controversial example. Maybe Steve Jobs. Or the Google guys. In any event, in a society in which all transactions are voluntary, nobody would engage in a transaction unless they felt (at the time they chose to act) that they would be better off (by their own standards, as viewed at that time) than if they didn't transact.
Now people can (and often do) make mistakes. People sometimes regret having transacted in a given way. However, I still believe that allowing people to make their own choices is more likely to result in outcomes that those people prefer than by having those options restricted or set by third parties.
A wealthy businessman then achieved his wealth through a series (sometimes a long and complex one) of transactions, in each of which his counterparts felt they profited (ex-ante). If the process took a long time (as it usually does), competition would surely have sprung, requiring the businessman to continue to come up with products that consumers prefer, not just to doing nothing, but also to those products offered by his competitors. The reasons for the preference could be quite varied. They may include better quality, lower price, higher reputation, convenience, safety, etc.
The weighing of various considerations is entirely personal. But however they did so, the consumers continued to choose to buy Mr. Gate's products over those of the competition.
I agree with your characterisation of the political system. I would point out two differences, one of degree and one of principle, between the political and the commercial realms.
As a matter of degree, the political system often introduces very high barriers to entry. After all, to sell a product, it is enough to persuade a small group of people to buy. To win elections, you have to persuade a very large fraction of voters to support you. Now admittedly with some products (network products), an established brand has a strong staying power. That's why the difference is one of degree.
As a matter of principle, in the political arena, people are free to make decisions without expecting those decisions to impact them personally. After all, your vote will virtually never determine the result of the elections. You are free to vote without seriously considering the trade-offs that that vote represents. That is not the case with consumption choices, where you immediately and personally pay the cost (and reap the benefits) of your choice.
Suppose I own the land on which a successful manufacturer or store operates. His success has made my property more valuable, since I now realize that more money can be made on it than I first realized. Therefore, I raise the rent. The land is now more valuable.
The successful manufacturer can (and often does) move his operations to be located in cheaper areas. It happens all the time. As a result, the land value as a fraction of the overall value of the operation will continue to fall. That is slightly less the case in dense urban areas, where the location benefits are great. However, overall, I would still claim that my statement is correct - land represents a diminishing fraction of wealth in society.
I don't know the history, but I suspect that this class has lost some of its legal protections and political privilege, and land ownership became available to others, but there are still land owners and non-owners. Just a population shift.
But that's critical - the initial (unjust) distribution of land ownership has not been maintained. Land is now owned by people who purchased it from its original (unjust) owners, largely using wealth that they created. The current distribution of land ownership has lower and lower correlation with the original (unjust) distribution. Rather, it is correlated with people's productivity in the intervening years. Over time, I assert, we will arrive at a distribution of land ownership that is practically independent of the original distribution. At that point, the original injustice will cease to play any effective role in society.
Free men are not equal and equal men are not free.
Government is not the solution. Government is the problem.
