If national insurance must fund social care, at least make it fair
Analysis: the government could generate an extra $20bn by reforming national insurance to tax high earners
The government could generate almost double the £12bn it expects to raise for health and social care if the national insurance system was made fairer, according to a group of economists.
Ministers could fix the system to make higher earners pay the 12% standard rate, handing the Treasury £20bn of extra revenue, according to a team from the London School of Economics and Warwick University.
