But we wonder about that assumption regarding Corporation Tax in the UK.
When Labour were about to introduce the minimum wage similar claims were made; businesses would suffer and some would fold it was said but that was simply not true.
Presumably business chiefs just want to make share the lion's share of profits goes to them and not the government.
As Social Security payments have been squeezed in the UK and public sector pay frozen under this generous Conservative led-government Chancellor George Osborne cut Corporation Tax at every opportunity.
So people were being told to tighten their belts due to necessary austerity measures following the global economic downturn of 2005 but big business was getting a hand out.
Today's Telegraph front page report is such that it even has an unflattering image of shadow chancellor Ed Balls and Labour leader Ed Miliband. But we all have such images and in order to offer balance will select our report image carefully from a wide-range.
With strict election campaigning rules in the UK where a letter by Tory donors and business buddies fits in the scheme of things is unclear.
It probably skirts the rules rather than breaking them but it offers ordinary people of the UK nothing.
It hints at job cuts and a broken economy if the Corporation Tax is raised, also hinting those involved are directly working for the Conservatives.
But it is all bluster, waffle and scaremongering.
