This will free us from an unstoppable onslaught of characterless chains and so give us the freedom of choosing between them, and locally owned shops.
While large chains provide benefits in the form of lower prices and more services, they also have their drawbacks. Smaller, independent stores are unable to compete and so are disappearing. This will lead to less choice and less innovation for the consumer. Our country will also loose these characteristic shops and see them entirely replaced with a few monotonous chains.
Big chains should be encouraged in some areas, such as out of town centres, as they lead to lower prices. However smaller retailers need supporting.
There should be different tax brackets on the revenue for retailers based on their income. This should be adjusted so that chains can still exist, but smaller stores can also lower their prices to compete.
