I'm from Australia which has similar probs. I look at it this way:
2001:
$USD10000 @0.49 = $AUD20408.16
convert it back in 2003 (now):
$AUD2040.81 @0.73 = $USD14897.96 (+48.9%)
That's an effective gain of more than 20% p/a. Great if you're investing in AUD, but I live off AUD so that means I'm LOSING that! I work harder so my USD income is rising each month, but at the end of the day the amount of AUD coming into my bank account barely changes. If it starts going backwards (with my USD income still rising) then it's time to get a haircut, and get a real job.
