Your post is so xenophobic, homophobic and misogynistic that I could not believe while I was reading it. For god's sake you are a moderator here and what you wrote is nothing short of hate speech.
Doesn't look like you know what you're talking about if you're blaming Trudeau for this. He repeated a line of argument that he has been feeding to the US media for a couple of months now. He has taken those arguments from Trump himself, where he last year said that imposing tariffs on Canada based on national security argument would be insulting. Before using it for the first time, he called Trump and told him that he was going to use that language. After he used it, he called Trump and again told him that he will continue to use that language until tariffs are removed. Now Trump's ego was bruised in G-7 and he didn't have the guts to complain in person, fine, that's understandable for an egocentric snowflake like him. But to blame Trudeau for this is just ridiculous and no sane person has, in Canada or the US.
Again doesn't look like you know what you're talking about? No tariffs? Even after opening up over last few decades the US is more protectionist than Canada. Take dairy that Trump likes to talk about. Canada charges 200+ percent on imports above a quota it has set. That quote is 10%. Below that quota the tariff is minimal (few percent I think). The US does the exact same thing. While Canada's import quota is 10% of dairy sales, US has a 1-3% import quota depending on the product, and above that quota assigns a very high tariff. The resulting outcome is that the US dairy exports are more than twice its dairy imports. And you think Trump is right about Tariffs and just hates Tariffs and quotas in general and wants totally free market? And all that is besides the significant subsidies that the US pays to its farmers, which is anything but free market.
Go on support Trump, but to think that he is for free trade is as simplistic as one can imagine.
And this whole idea that the market is smart, and whether the market picks something or not is an indication of the true worth of a product is, well, clueless. Yes the market can be the smartest if you have a truly free market, which for all practical purposes is impossible. Apart from all the little ways that people interfere with a truly free market (like tariffs, quotas, subsidies), and apart from the clear stupidity of the market in picking good from bad in many situation (e.g. subprime crisis), you can never have a free market because you cannot appropriately internalize all externalities. When in North America we use more energy to drive our cars than anywhere else, we're in effect receiving a subsidy by not paying for the damage that we cause to world's climate. When we import our steel from China, we're receiving a subsidy for not paying for the damage and death that that steel factory imposes on Chinese population. When corporation accumulate wealth in the way they do, they receive a subsidy by not accounting for the societal cost of the inequality gap that they continually work to increase. So no, the market is not the smartest, not even by a long shot.
