This simply isn't true. The connection is illusory: it would only be true if particular sources of tax were used to fund particular programs of expenditure (e.g. income tax funding social welfare, as you are trying to imply). This isn't the case: there's just one big pot tax flows into and funding out of. It’s not even the case for things like car tax; if motoring taxes were all spent on road infrastructure, we’d probably have the best roads in the world.
You could equally ponder why direct supports to business are high, when corporate tax rates are low, but presumably that doesn’t fit the agenda.
