Eva, yes I can deny that because it is not true. You probably do not know what exactly the business cycle is--I take it that you have no formal background in economics.
Spending was given a boost by tax cuts, not the business cycle. Business cycles, by their very name, are CYCLICAL, which implies longer trends pre and post-tax cuts. Also, as I said in previous posts, the USA represents only 20% of the world economy. Even a tax cut in the USA can't prevent a recession if 80% of the rest of the world were to have tax increases (hypothetical). The fact is the global economy has more sway over the global business cycle than what a tax cut has in a nation (the USA) that represents only 20% of the world economy.
Tax cuts are a good thing--we agree. But it is not true that "a tax cut gives the business cycle a shot in the arm".
Business cycles sound intriguing...I once had a landlord who said they were important, but he didn't tell me much about them.
