Exchange rates really don't matter much for most people. Most people buy goods at home. Relative strength and weakness of a particular currency against another just indicates whether imports are more economical or whether manufacturing at home + exporting are more economical. This change over time is reflected in both exchange rates and accounted for in PPP adjustment. It may fluctuate over time, but I don't think that's a huge deal when deciding which country you plan to work in.
