If the government open the means testing box all hell will break lose. It would actually be quite funny if all parents were now told they had to pay for transport to school! Oh the outrage!
We are already seeing people adjust how they work due to tax cliff edges. There will be parents who cannot afford the fees with the increase and some will give up work/go part time when they move to state. Many families pay as they go and any change such as redundancy can mean they have to move their child.
This is simply another consequence of this policy. What I find most worrying is that there seems to be no acknowledgment or planning of what the consequences would be of this and other policies Labour have brought in. The NI increase being a good example.
The people paying all the tax don't want/can't afford to pay anymore. If Labour keep poking them it won't end well.
