From the Cato Institute:
So far Occupy Wall Street and its imitators across the country have directed their rage at Wall Street and the rich in general. But they would be better served if they aimed their criticism at the true authors of this country’s problems: the politicians in Washington.
[I]t’s not just debt; it is also the size of government. Numerous academic studies show that when government grows too large, costly, and intrusive, it acts as an economic anchor. For example, a pair of studies by Harvard’s Robert Barro found that “public consumption spending is systematically inversely related to economic growth” and that there is a “significantly negative relation between the growth of real GDP and the growth of the government share of GDP.” Similarly, an empirical analysis of 23 OECD countries by Florida State University economist James Gwartney and his colleagues found that a ten percentage point increase in government consumption as a share of GDP reduced the growth rate of real GDP by one percent. In other words, as government spending goes up, economic growth goes down.
