Republican presidential candidate John McCain recently proposed a "gas tax holiday" this summer to give drivers and vacationers a break at the pumps. The Association of Equipment Manufacturers (AEM) released a statement on why they would oppose such a measure, citing its detrimental effect on the road building/repair industry. Other groups, including AAA, criticized the measure. InÂ today's down economy, there are plenty of ideas floating around about ways to bring back a boom time. One article I found particularly interesting ran in the New York Times earlier this week and described a proposedÂ tax break for first-time homebuyers as aÂ way to stimulate the housing market.
