Without these additional burdens, income tax for those earning $72,333 per year or more has risen this year, as has sales tax in Britain.
"I certainly accept that it is a tough time, absolutely. What I do see also in those forecasts is that unemployment will fall, employment will grow and growth will be there in each year," Chancellor of the Exchequer George Osborne said.
