Ridiculous post. Entire BOOKS have been written about the rich culture, the self-sustaining way of life, the fascinating mythology of the west coast peoples.  If these people "HAD no culture" then gosh, why did those good Anglican and Catholic churchmen go to so much trouble to stamp it out? Even AFTER the small-pox and the liquor ravaged their way of life.  

They didn't have plows--because this society was not agrarian.  Simple as that.  People who live hand-to-mouth don't stop to carve and raise intricate totem poles to celebrate their families and their mythology they took the time to create, or to construct substantial communal houses against the weather, or go to the trouble to stage elaborate gift-giving potlatch ceremonies. They don't  weave baskets, create ornaments,  make their own clothes--including hats. Carve seaworthy canoes.  

But your ridiculous post is very instructive, Goober.  
Man, Canada's got a long way to go...
