I guess I get what you are saying, but it doesn't seem like something that everyone will benefit from. It is like something only shop owners can really enjoy.

-More shops in a mall with lower costs per shop
-Cheaper shop costs
-Newer/More/Poorer players getting shops
-Lower prices
-Newer Players can afford more and make more money, buys a shop.
-All this results in a higher flow of money and a stronger economy.
-----------------------------------------------
Some towns might even build apartments which could (possibly) create a real estate market, that would be great for the economy.
Lower taxes can be on apartments because upkeep isn't as high per plot, ideal for new players.
All this would be amazing for an economy.
