I agree.
It would be farcical to have spent multi-millions on a prison just to have a few inmates. At a time when the Isle of Man was awash with cash due to overpaid VAT, the arguments were made for a super dooper top-notch prison (in much the same way we have an exceedingly expensive New Hospital, New Power Station, New 'All-Island' Sewage System, New leisure Centre and New Incinerator. Other stuff too). Put quite simply, all those well-paid prison workers salaries and pension and the huge capital outlay have to be justified.
