I'm probably being unreasonable here but it really frustrates me when people say 'we manage on a salary of £24k' etc but conveniently forget to mention the tax credits, child benefit, subsidised school lunches etc that bumps the salary up considerably.
On threads where someone says they struggle earning £50k there are always posters who are incredulous and outraged that people aren't living like kings on that but fail to realise that there would be little to no help for families on that wage whereas the lower wages are propped up with tax free benefits and housing pay that means they have more disposable income than the on paper huger earners!
