Minimum wage was bitterly opposed by the Tories in the 1990s. They only changed their mind after it was introduced, and because it was so popular.
It will probably happen the same with basic minimum income.
See book by Guy Standing: basic minimum income saves money, promotes creativity, entrepreneurship, wellbeing, and economic growth.
Bankers getting bonuses from public money after the banks failed is stealing. Ordinary people being guaranteed food and shelter is a civilised society.
The interesting thing is that right wing think tanks and politicians are beginning to support basic income: to avoid a more radical revolution. I think it’s pretty inevitable to happen. The argument seems to moving on to how to do it rather than whether to do it.
