In the UK we had many communities thrown on the scrapheap with mines, steel and much else manufacturing gone. Initially people invest their redundancy money in things such as a new dog-grooming business, a cafe, a shop, perhaps a tattoo parlour, depending on what 'follow your passion' leads to. So these businesses go okay for a while, eventually the redundancy money runs out, or, in rare instances, the 'follow the passion' business actually meets a genuine need and a success story happens.
Around the time of this general decline my sister was trying to raise money to go somewhere fancy with her group of friends. Being skint she decided to raise some money by making things - things with beads, jewellery, that sort of stuff. These items sold 'well' but only to her friends whom she was going to be travelling with. There was no 'external market'. So rather than go on the big trip to the festival they missed out on that and spent what little money they had on beads etc. to make stuff to sell to each other. A lesson in economics was learned the hard way.
To some extent any town/city/country that does not have manufacturing and external markets will be a variant of my sister's schooldays model of capitalism. If manufacturing (or mining) jobs go and retail comes along to 'fill the gap', then it cannot last forever. Tourism can't come to the rescue either.
