With reference to Roger Pulvers' June 1 Counterpoint article, "Is aging Japan really ready for all the non-Japanese carers it needs?": While I realize there is a good argument to be made for employing foreign nurses/carers, given this country's aging population, these should be only allowed in as "guest workers" on a contract of fixed length -- say three or five years -- after which they should be required to return home with no "ifs" or "buts."

It's instructive to study Germany's guest-worker system and how it failed, resulting in an unwanted and alien Turkish community in that country.

Simply do what it says on the box: "Guests" do not stay forever! It would be a great pity if Japan made the same disastrous mistakes in this regard as my own country, Britain.
