Using the tax system (ie. Tax Credits) is the wrong way to help those on lower incomes, the idea of the national minimumn wage, was to ensure that all workers, regardless of industry, would be paid a fair livable wage.
Using the tax system to supplement low wages is the road to hell, it offers no real long term benefit, all it does is ensure that the tax take on those who are not on the Tax Credit system continually rises.
If you believe Gordon and his cronies that this system is sustainable long term, you must be forgetting that most of the so called improvements in this country, have yet to be paid for, sooner or later that money is going to have to be paid back, he even had to change the economic cycle, in order not to break his own rules.
Whilst in place, anybody who can claim Tax Credits, should do so, that is not the issue, as far as I am concerned, but long term, this is a disaster waiting to happen.
