BA are paying MF market rate +10%, so why do people think that the new recruits are going to be below the poverty line, when Easy, flybe & Ryanair all seem to manage to crew their aircraft.
It's quite simple really, non of the airlines you have quoted are based in London, to operate on MF you need to be within a fairly close proximity of London - the average wage in London is £32,604 per annum and £26,728 in the South East.
