:) Sadly your post is almost entirely false. Much smaller changes can affect a person.
Canadian's have seen a large drop in their purchasing power in the US recently with much smaller changes than your imaginary 20 orders of magnitude fluctuations, what every that actually means. Regardless of what you are trying to convey, I'm pretty sure you don't mean 20 orders of magnitude:)
Many of us have US property and visit for the winter, the 30% rise of the US dollar against eh Canadian has a profound effect on us. We also import food from the US, this has had an inflationary effect on our food prices.
or put another way, for Canadians, alot of things just got 30% more expensive over the course of the past year. That's a pretty big deal!
Similarly for American's who come to Canada frequently, things just got much cheaper! If you are American and in manufacturing where you sell your goods to other countries, your prices have gone up recently due to the currency fluctuations, making you less competitive and lowering your profit.
The only part of your answer that I'd consider partially correct is the last sentence, and even then there is a huge caveat, that it really depends on what you do for a living, what you buy and where you travel.
