Let us reform the budget so that some day the working poor will pay no income tax, so that some day seniors on fixed incomes will no longer fear the taxman coming, so that some day all taxpayers will pay the same percentage rate of taxation, so that some day the federal government will live within modest means and help rather than hurt, and so that some day we will have viable universal medicare for everyone.

The context states that if the budget is reformed then 'the working poor will pay no income tax'. The system did likely not understand the phrase 'take home more of their pay' as meaning they will pay less tax.
