First, the government proposal to raise National Insurance rates to pay for social care has no mandate, as it breaks the Conservatives pledge to “not to raise the rates of income tax, National Insurance or VAT” in their 2019 election manifesto.This is part of a pattern characteristic of this government's disregard for truth, integrity in public life and the rule of law.
Second however, a rise in National Insurance, unlike income tax, affects everyone working, including those earning the minimum wage whose income would otherwise come under the taxable income threshold. As such, it is likely to disproportionately affect the poor and young earners in particular.
Funding social care from National Insurance, is therefore both iniquitous and regressive, or as one letter to the Guardian perceptively pointed out, “It is the poor paying, so that the middle classes can hang on to their houses”. It is also worth pointing out, that the retired, some of whom have very generous pensions, whilst paying tax, do not pay national insurance.
It would be much fairer to fund social care from marginal increases in direct taxation, at higher income levels, excluding those whose annual income is below £23,250, which is the level below which government will step in to fund social care costs.
