I think some Americans should pay higher taxes. I also think the government needs to stop spending so much.
Taxing the price of gasoline alone will not fix the problems we have here. Taxing 5% higher to the top 5% income bracket however...
And I'd just like to point out that the US is incredibly spread out. People in places like New York can take a subway or a cab...they're everywhere. Here in Phoenix (a city that covers over 3,000 square miles) we have a light rail that they just put in. However, the light rail doesn't even reach the northern part of the city, where people live. You still have to drive to a park and go location and pay to park your car there all day while you take the light rail downtown...because that's the only place it goes. Not out to any other parts of the city where people work. There's always the option of the city bus...if you wanna plan out a route that includes changing buses seven or eight different times and involves probably having to leave your house before the sun comes up to make it to work by 9am. And those buses are disgusting. The city does nothing to keep them clean.
It may be feasible to publicly commute that way in condensed cities, but most of the cities in this country are more spread out than that. Not to mention the fact that a lot of the southern locations in this country are hotter than hell, so even if I worked say 2 or 3 miles from home, there's not much I can do about it. I believe in the month of July we had a weeks worth of days that were sub-100 degree temperatures, and every single one of those was above 95*F. So until you've lived here, don't act like you know the solution to the problem. I would never claim to know how to fix the UK's problems. There are a lot of things that need to happen to fix the economy and the debt in this country. Doubling the price of gasoline, however, is not it.
