$286.4 billion ?
As in, which a B? Dang. That could have funded an entire invasion of a small to medium sized country for a decade. Even with KBR's graft.
Seriously, tho. All these new highways... where's the land gonna come from? Me thinks emminent domain will rear its ugly head. How much do you wish to bet a very large amount of private land will be "bought" at gunpoint for pennies on the dollar? Except for those whom are well connected to the Powers That Be, who will receive dollars on the penny.
Soon enough no one will be able to afford to drive on said highways. I remember, what? Two, three years ago gas being around a $1. I see $2.50 a gallon all the time. Sometimes as low as $2.25, sometimes as high as circa $2.65. About $1.50 jump in two or three years. In two or three years, gas prices hitting $4.00? Ouch. That will throw a spike into our economy.
People will pay whatever they have to for gas. It could be $15/gal and people would still buy it. They'd just make adjustments in other areas of their life. Instead of that big hurkin SUV, they'll drive a mini-van or wagon.
I'm sure you are mostly being sarcastic.
Ah, people usually do think of oil just in terms of gas for their car. Not completely true. A barrel of crude oil is cracked into many different products. From tar and asphalt to gasoline and kerosone. Plastics come from oil. Glance around you and see how many products within your line of sight are completely or partially plastic.
If the price of a gallon of gas hit $4 or $5, our economy would be very drastically hindered. Diesel is almost more important than gasoline. Some could argue it's far more important. How do you think food gets to the grocery store? When the price of diesel goes up, all prices go up to some degree because almost every product or its subcomponents are transferred by truck.
At $10 per gallon (in today's dollar value), almost all non-essential businesses would not be economically viable. Of course, by that point, any cheaper alternative would be taken. Gasoline would simply not be an option.
