The EMBOLDENED phrase is a matter of balance and opinion - as is everything in life of course.
No time at all for what I took to be rather a cynical statement in the underlined comment.
Your viewpoint is interesting, because it can be argued that the policy for school lunches as announced is the first piece of real politics that Corbyn's team have come up with.
As an actual policy, it has significant flaws. It's not costed through, and the amount raised from private schools in the manner proposed is very unlikely to raise enough money for the headline proposal to work. In that, it could be described as 'fucking daft' because it won't work in government.
However, as
politics (particularly opposition politics) it works rather well. It's redistributive, and the majority of the electorate like redistribution when it's from a section of the populace that can be described as 'rich' or 'not them'. (The points made above about the many people who use private education whilst not being remotely rich are valid, but the voter doesn't make this distinction easily). The provision of free school meals is what our American friends would characterise as 'no-one is ever against Mom and Apple pie' - i.e. no one can object to the objective. It puts the Tories on the back foot - they can't argue against the free lunch part without being further heartless, they can't endorse taxing private schools, so they have to think of a valid response - and since they are in government, they have to cost this response. It opens multiple lines of attack for the Opposition - the Tory stance on poverty, the recent benefit changes likely to put many more children into poverty versus Labour's record* in lifting 900,000 out of poverty. Education cuts can be highlighted, with all the research showing that under-nourished children are much less likely to learn well (yet Brexit means we should be investing in 'our own people' surely, prime minister?) The well-off being able to obtain much better education than is available to the majority (and harp on about inequality and tax breaks for the very rich). The unwarranted status of private schools as charities. And so forth.
So it's a proposal that is in effect, a lie, because in government it will be hard to implement as described. But it wins all round as effective politics. Yes, politics is a cynical profession. I would still rather have a government that could implement a policy like this, but compromised by reality, than an opposition party that is too pure to grub around in the matter at hand, to wit, winning power from the Tories.
