Will the price of gas ever be in the $1.50 per gallon range like it was in the late 90's? If so, when?

I don't think we will see gas at that level ever again. I'd expect that alternative energy sources could be developed but by the time they are, inflation will have raised prices too.

Wired currently has a story on why high gas prices may be better for the United States. It may be worth reading.

as soon as you find out the price of tea in CHINA.

I doubt it. Unless the time machine is ever invented.
