Anyone who really thinks that benefits here (in/out of work) plus free healthcare, free education and free housing isn't a draw to economic migrants (especially those who claim asylum) must be living on a different planet.

Keeping earnings down clearly avoids tax and increases various benefits/tax credits and other entitlements such as free prescriptions, dental care, school meals etc. I really don't see how migrants in this category are a net benefit to UK PLC.
