Local authorities want to see more diverse and vibrant high streets, but they're economically reliant on charity shops - local government collects and spends business rates, but central government funds the rates relief that charity shops receive. They simply can't afford to offer rate relief to other tenants who might use that space to build a more valuable business, because the tax system has distorted everyone's incentives.
In many towns, charity shops are visibly crowding out other kinds of retail. The relief for charities props up landlords and local authorities, taking away the urgency to reform the system and take steps towards a more sustainable future for declining high streets.
The new government are finally talking about fundamentally reforming the business rates system, but it's happening at least a decade later than it should have done.
