I'm not sure what government has to do with it, it doesn't set the price of rents.
Rents do get progressively lower in distressed areas because they are distressed, and higher in high demand ones, but that's not enough when less customers are entering your shops anyway.
Government adds mountains of red tape, taxes employers to death and has reduced the spending power of the median worker to below poland through its plantation migration policy.
Commercial units sit empty instead of lowering rents because of the 'extend and pretend' in lending. The banks can't afford to revalue commercial real estate at the current market rate. It's like the 70s again.
