I believe this idea is innovative in several other countries except in Korea. There had been a standard oil monopoly in America by John D. Rockefeller. Similar thing has happened currently in Korea by a large supermarket company which is similar to Walmart that sells items really cheap compared to other markets. Also it has been an issue by the government and other small individual markets because the company dominates the other small individual markets by offering comparatively cheap prices with numerous markets.
These days, Walmart is in almost every town but it's too big to fit in close to people. So many people have to drive at least 5-10 minutes to get to the super market. If the stores that sell for cheap are close to where you live that you can walk there, it will be popular to many people because it's cheap and close as markets near where you live. The company should be big as Walmart but make smaller and more numerous markets everywhere in many towns and cities. The store not only sells items like Walmart but also sells fast foods and coffee cheaper.
Such stores are already in Korea dominating small individual markets which widen the gaps between wealth and poverty but people who made such stores can become really rich. When the company also sells doughnuts, fast foods, coffee cheaper, then profits will increase that were used to be earned by some weak chain stores and individual markets. People haven't tried this yet because it's new and innovative. Also it's possible because the company in Korea succeeded. Even Korea has capitalism like many other countries including USA.
Our markets will keep posting compared prices of items from near competitive markets to show that our store always sell cheaper and it requires fast and exact information. Inside the markets, they will be playing updated top musics everyday to help people enjoy shopping. There will be an app for smartphones keeps updating items that are on sale and daily deals and let people order online or on the phone.
