False.

You don't need to increase taxes to increase wages - you could actually collect the taxes that are due but being funnelled off into offshore accounts, you could limit the bonuses being paid to CEOs while workers struggle to heat their homes, you could cut military spending, you could not give £35B of public money to a few mates in exchange for them pretending to supply PPE. The list goes on.

You do for public workers assuming all else equal; if you fix the corruption you point out, that will always help regardless of the situation present and it would constitute a new baseline from which taxes would have to be risen.
