Yes, "higher salaries" as in higher tax band (median salary is 39k, higher tax band starts at 50k), which impacts 16% of people. That's why it has an notable impact on sales and also on the used cars market (salary sacrifice schemes are usually PCP/leasing over 3-4 years).

Perhaps it is the "London bubble" on HN as I feel that no-one is registering that 100k+ is a really, really small minority...
