# Are currencies equilibrating?

I was travelling recently and realised that dollars, euros, British pounds and Swiss francs all have more or less the same worth (i.e. 1 dollar $$\cong$$1 pound $$\cong$$ 1 euro $$\cong$$ 1 chf). This was not the case when I was a child.

Is there a trend here or am I interpolating to much? Are different currencies evolving over time towards all being equal?

PS: Please don't just answer 'yes' or 'no'. Whatever the answer is, I will wonder why it is so.
