If we wanted a thriving market culture, we could have one - obviously shoppers would need to use them regularly. I think that making them more accessible and convenient would help. Changes would have a cost, so there would need to be demand.
Councils could offer to refund some parking if shoppers spend a minimum amount at the market. Opening times need to fit with when people are available to use them.
Great markets often have food at their heart - selling ingredients such as fruit and veg, meat, fish, bakery, dry goods, deli items, not just coffee and takeaway stalls.
Compared to cultures that have thriving fresh produce markets, the UK is generally not so flexible with what food we buy. For a lot of us, the cost of living means tight budgets and a feeling that we cannot afford to make purchasing mistakes. Buying something in a paper bag, feels like a risk compared to a supermarket plastic pack with cooking instructions and a use by date stamp.
A lot of people in the UK meal plan too, not always, but sometimes because they don’t have the confidence, cooking skills, or a well stocked pantry. They are not able to create meals around what is in season or whatever is a bargain that day.
All of this is fixable potentially, but is this a priority for many people?
