It’s self defeating as well and it’s pretty immoral, what ever side of the debate you’re on. It highlights the lack of financial education in the general population as well as it’s probably the most abhorrent way of generating more revenue from income tax. People considered too low paid to pay tax, suddenly paying it, due to inflation rather than an upturn in their circumstances, yet the public doesn’t really see this for what it is.
Whilst I don’t agree with it, increasing income tax, then cutting NI (which was the floated idea) is a more coherent approach if you want to raise tax, but soften the blow for the lowest paid.
