That's an excellent question Thought, and theoretically identical goods should have the same real price. There's actually something called the
"Big Mac Index" that measures the very concept you're wondering about, which is heavily related to
purchasing power parity.
The Big Mac Index historically shows that, in fact, people in different countries are
not paying the same real prices for identical goods in many cases. I tend to attribute the real price difference to local cultural factors -- the demand for a Big Mac in the US is going to be different from the demand for the same product in other countries. Note that the Wikipedia article shouldn't even mention India, because it's not even on the Big Mac Index list: can't serve beef in a Hindu country (I think?), and it is difficult to compare vegetable burgers or whatever Indian Big Macs are made of to the burgers we chow down here.
Regarding the price of gasoline, yes, it's definitely impacting what people want to drive. General Motors just shut down some plants in Ohio, though their factory in Lordstown, OH, which produces the little Cobalt, is doing wonderfully. Though I don't know what nuclear families with more than three small kids are going to do -- they almost need the SUV or some type of minivan to travel anywhere as a group, unless they constantly hire baby sitters.
Getting back to politics, I fear there are a significant number of Hillary supporters who will choose to remain at home - or even write her name in out of sheer spite - rather than vote for Obama on Election Day. The pundits and the Democratic Party itself shy away from considering this, but it is a very real problem. A large part of this attitude stems from the perception that the media treated Senator Obama as a demigod while practically ignoring Senator Clinton -- an objective review of the media coverage would show that this is clearly not the case (Rev. Wright, anyone?), but the attitude is there, and it is vicious, and it is dangerous. Plus, Hillary did garner a majority of the popular vote in the Democratic contest, and this resurrects shades of Gore v. Bush in 2000. Thus, I continue to feel that the VP slot for Hillary is necessary to heal the very real divisions within the Democratic party right now.
Let nobody be fooled by the 20,000+ crowd Obama drew last night compared to McSame's 200 or so in Louisiana: the future of our country
is in serious jeopardy. I worry that the media celebration of Obama's victory will lull those inspired by this wonderful candidate into a sense of security, of certainty that their man will win and nothing can stop him.
We must all be willing to donate some time to the Obama campaign, whether that means making calls, doing data entry, or getting on our feet and canvassing on his behalf. For those who are inspired by Obama but prefer not to be affiliated with the Democratic Party, my advice is to buck up and visit your local Democratic campaign headquarters anyway,
because this is too effing important. We
need to push Obama into the White House, because otherwise we young people are going to find our asses shipped to Iran. I already worry enough that the Bush Administration will launch an airstrike just before Obama takes office, thus forcing Obama to fight another war whether he likes it or not.
EDIT: Actually, now that I've examined some blogs ZeaLitY refers to below and completed my own independent investigation into the matter, I have convinced myself that Hillary did not win the popular vote as she and her campaign officials claim.
