Anger over mainland visitors is bubbling over, as public outrage at cross-border traders and mainland mothers goes through the roof.
There is talk that there should be an upper limit on the number of tourists coming across the border, the precise number to be set by the government. This suggestion is not feasible and frankly, quite silly.
First of all, how high should the upper limit be?
No matter the amount, there will be extremists who think it's either too demanding or too loose. It will be difficult for the SAR and the Shenzhen governments to come up with a number that will satisfy Hongkongers and mainland tourists.
From an economic point of view, setting a limit is very risky. It will be difficult to gauge the effect of the limit on the tourism industry, and the whole economy of Hong Kong. It could be a disaster, as hard-hit luxury stores which relied on mainland tourists close or cut staff, which will inevitably spill over to other industries.
Last but not least, should a limit be agreed on, policing it will be a nightmare.
