All the Tariffs are really going to make poorer people suffer not only here in the U.S. but all over the world

Tariffs are often what start wars between nations historically. It's good to know this to begin with. Because if other countries cannot sell their goods to the U.S. because the tariffs make them too expensive for Americans to buy then they likely will put tariffs on whatever goods the U.S. sends to them too.

So, generally, Tariffs are thought to be counterproductive for this reason.

So, Trump wanting to tariff every nation just means he is starting an economic war that could turn into a bloody war either directly or through proxies any minute or any day after those tariffs are put in place.

However, there is another way to look at all this. Very few nations can survive without trading with other nations. 

What are two nations that are somewhat okay with no trade with other countries?

The U.S. and China and the European Union likely could all survive without trade with other countries except for thing like Oil for gasoline and Diesel, for example.

So, the biggest problem for the U.S. if they tariff Canada for example, is that gasoline in the Northeast and Midwest of the U.S. will likely rise in price by 50Cents or a dollar if Canada is Tariffed the way that Trump is talking about now.

So, who really suffers the most from Tariffs of all kinds here in the U.S.?

The lower 50% of income people.

So, what will happen is food will cost much more because the gasoline and diesel used to drive it to them will cost so much more because of Tariffs against Canada to begin with. And the costs need to be passed on to the consumers for the suppliers to stay in business so the poor will suffer incredibly from the tariffs more than anyone else.

Instead of an 18% rise in homelessness I think it is going to increase under Trump to 30% increase in Homelessness within the next year or more here in the U.S.
