Whilst I sympathise Aiden, and I believe the system will simply strengthen the requirement for you to prove you can support your family, I do feel that if you can't support your family, why should you expect the country to let you in and you require support from the government. This in the same way as why should we be supporting people who come from abroad and are given houses, cars and money.
If they do implement the system, it needs to be fair, but it will probably be unfair.
