I can see the point of doing this as:
Schools Cost = £££
NHS Cost = £££
If the state is just handing these services out for free to those who should & could be paying, how is that fair? Not very progressive for those poorer members of British society to be having their allocation of state resources decreased by those with no entitlement.
Unless we believe in the magic money tree whereby everyone can have everything because supply and demand don't really exist in the socialist mind set.
