My eye started physically twitching when that wage inequality was called "irrelevant" on @ThePledge.
Earning £3.5 million instead of £2 million doesn't make you better at your job.
Whereas earning e.g. £17,000 instead of 16,000 almost definitely would.
Closing the wage gap wouldn't just be fairer, it makes economic sense.
An extra £1,000 a year for someone earning very little could help with childcare, transport, and even diet/nutrition. All of which would help them be more productive at work.
An extra £100,000/year for a FTSE 100 CEO wouldn't have anywhere near the same effect.
