schemes such as this will benefit working class taxpayers because it's one less thing they have to worry about paying for. A day out with two adults and three kids can be expensive by public transport and not every family has access to a car; by allowing the kids go free it may allow some families to afford to have a day out that would have otherwise been unaffordable. The money saved might then be spent on other things like fish and chips, ice cream or whatever you care to mention
Sorry, but no. If there is anyone who knows that a child's bus fare is buttons compared to how much ice cream, fish and chips and indeed literally anything you might want to purchase on day out costs, it's working class parents.
Although to be fair, it might cost the same as a plasric inflatable or some other type of plastic tat. Another win for the environment, since such things, in working class families, tend to be one use only. If not left at the beach, they are stuffed in the wheelie bin at home.
It takes time and money, and most of all space, to have the luxury of being organised enough to ensure your plastic tat is correctly stored at home between seasons. And of course, it's far easier to transport such tat, if you have a car. Hence why some bus users leave it the beach.
Free bus travel wouldn't remotely factor into whether a truly working class family can afford a day out, even if they only had one kid. How do we know this? Because that's exactly what the rich, out of touch, wouldn't know a working class family if they tripped over them, politician, said this scheme is for.
