For a given value of 'easily'.
As we aren't allowed to know the full cost of each of these white Dumbos, and we assume a conservative £100,000,000, that's a tenth of a DUPbung or a magic money shrub.
Or in real terms, about 30,000 people on £30K will have to work for an extra year to pay £100M in tax for it. So, not really 'easily'. Hands up who's willing to do some overtime.
