But back to Obama’s proposal, such as it was. If Congress should actually change the depreciation rules for corporate jets—rules that were set by the Obama Democrats’ own 2009 stimulus package—and it had any effect at all, the costs would be borne not by clueless CEOs or other high executives, but by comparative little guys: the pilots, flight attendants, mechanics and ultimately the folks that work the assembly lines at small jet aircraft factories. That’s what happened when Democrats in 1990 thrust a big tax on yachts over a certain size. The rich people who could afford them weren’t inconvenienced, but the folks in Maine and other places who build large boats lost their jobs. As a result, Democrats scrambled to repeal the tax. CEOs are not the only people who can be really dumb sometimes.
