Thanks for the lecture.
It's not a lecture, they are facts.
The Welfare Rerforms are also aimed at abuse from those using the EU rules to be in the UK. e.g. Those spoken about earlier by MPs in a radio show, who pay little to no Income Tax by claiming they are self employed, but expect to have bill free use of the NHS for themselves and their children and state schools provided for their children.
Some of these people, not all, even go further and use their tax breaks to declare a low income, and then ask for low income based benefits too, e.g. Child Tax Credits, Housing Benefit etc
Abusers always gets the rules changed. The law to change can use the NHS bill free had to come in and the same with the Welfare Reform laws and all the new planned changes to stop abuse.
