How about a comparison with another industry? Look at the supermarket trade and the 2 stores in the UK that are rapidly increasing turnover are: ALDI and LIDL - in the Grocery trade - the 2 LoCos.
Interesting comparison. I have read some analysis recently that the LIDL/ALDI model will run into difficulties in the long term because of the aging population. Going low cost mainly attracts a younger crowd, in whatever market you are. With an ever older population, more traditional business concepts (full service etc.) will become more attractive again as "silver agers" are willing to spend more and go for quality rather than price.
