Besides dairy, one of the last major quota based protected industries in Canada was the taxi industry. It's interesting to compare and contrast the two. It used to be that if you could put together enough of a down payment to get a loan to pay $1M for a taxi license or for a quota allocation for 20 cows you'd be set for life, as long as you were willing to put in long hours. We had no qualms throwing the taxi drivers under the bus, but are willing to go to the mat for those dairy producers. Is it because taxi drivers were mostly brown skinned?
Food is much more important on Maslow's hierarchy than taxis.
Without food sovereignty or at least multiple external sources of supply, we don’t have real sovereignty. While I may or may not support supply management, I don’t support any arrangement which could permit the USA to gradually undermine the Canadian industry and eventually become the dominant supplier of a key source of Canadian nutrition.
We now know that if we allow other countries to have undue leverage over us, they will eventually use it against us. Have to think long term here. What kind of Canada will my grandchildren inherit?
