oh, you would have paid £1000, but we now give people who have children £120 so your holiday is now going to cost £1120. Their holiday is going to cost £1000 and also we are going to repay the fine they have to pay with the extra £120 we are taking off you.
you think that is how it will work?
If you are talking prices then yes, maybe prices will go up, by about a tenner, across the board, so they maintain their profits. That's normally how it works (you only get free cheese in a mousetrap!). But the family going on holiday will also pay that increase. It's not like they will remain at the lower figure AND get the payment of the fine, wiping out the extra they paid to the LA, while the couple without kids pay the higher price.
Where is the loss specific to those who don't have children? Where is the discount (as opposed to the 'making whole') of the people with children? You clearly feel there is one, and you feel it strongly - it would be so easy for you to explain, with illustrative figures, how that is worked out.
I am very happy to say ok now I understand what you mean, fair enough, I apologise, I'm with you - if I can understand the maths you are using here.
