I wish I had a time machine.

I could go back a century, before the dollar allegedly lost "96 percent of its value" thanks to the Federal Reserve System, and buy the things I want at amazingly low prices. I could walk into a Best Buy store in 1910 and buy an iPad for $20, for example. I could get a root canal, if I need another one some day, for about $80. I could even buy a Saturn Sky sport car for $1,200.
