Government doesn’t "intrude" on the "free market." It creates the market.
Those who argue for "less government" are really arguing for a different government—often one that favors them or their patrons.
The critical things to watch out for aren't the rare big events, such as the 2008 bailout of [Wall] Street itself, but the ongoing multitude of small rule changes that continuously alter the economic game. ... The "free market" is a myth that prevents us from examining these rule changes and asking whom they serve. The myth is therefore highly useful to those who do not wish such an examination to be undertaken.
