It works for Tiny Islands who can massively increase their number of taxpayers. For the UK I really doubt it, but it is a Tory policy (having the lowest CT rates in Europe). It is also what the "libertarian" element of Brexit want. Cut taxes, Privatise (introduce patient charges to) the NHS etc.
It can work for the economy of any size, if it has already unusually large taxes and if the expectations are small enough.
Clearly neither is the case for UK.
