the mind does boggle
(figures are close but not exact)
Eu migrant comes and takes a low paid job say 13k a year
say he/she has a spouse and 2 children out of the wages he /she earns will pay about £120 a month tax while claiming full working tax credit. Around £30 a week and Child tax credit around £90 a week total £120 a week.
Net result the uk is effectivly paying them £360 a month out of tax payers money to come and work here
as i said the figures are not exact but they are not far off the mark
