I apologize in advance for sounding like a condescending bleepard, but you don't know what you are talking about.
Did you look at the graph I posted? There is only "so much" trade one nation can do with another. Canada is not big enough nor does Canada have enough demand for our products that we can just move all of Mexican exports to Canada. Similarly, we are a free market economy and if what you say is true (i.e. other countries want our goods) then there is nothing preventing us from simultaneously trading with Mexico and those other theoretical countries in your hypothetical argument.
The Mexican government is not intentionally flooding our nation with drugs and fifth columnists (whatever that is). We are a Capitalistic Society and Cocaine has a 10,000% profit margin in this country so you do the math on why we have a Drug Problem. As much blame we want to put on Mexico for the drug problem they can point the finger right back at us since it is OUR CITIZENS that freely and willingly spend so much money for drugs. If drugs didn't have a 1,000% to 10,000% profit margin in this country then drugs would not flow here. So there is enough blame to go around. Our government and citizens are just as liable for the drug problems here as Mexico.
Because it's a free country and I can do with my money whatever the bleep I want!!!
Two of the basic principles of the GOP are (or at least they were):
-Limited Government
-Free Market Capitalism without Government interference
So if you are a Conservative you should be sickened at the prospect of the government doing anything in regards to the Free Market. And this should be doubly so with the government telling you what you can and can't do with your money.
What do taxes have to do with me wanting to send money anywhere in the world that I want to?
The whole WTO, Globalization Free trade, tariff free, duties free, outsource, automative is a a very modern post-wwII scheme to bring about a single world economy, historically our nation has depended on protecting our industry, and jobs from cheaper nations being able to dump their products into our market, and flood it with cheap goods, where we can't compete, and puts people out of work, we kept Taxes & regulations low historically to allow domestic competition, while generating revenues from Tariffs, and Duties, and using protectionism to protect our industries. George Washington, Abraham Lincoln, William McKinney, Andrew Jackson, Alexander Hamilton, Warren G Harding, Calvin Coolidge, John Quincy Adams, Henry Clay, TR, Ussualys S. Grant, James Monroe, etc. We're all either supported Tariffs or were trade protectionists, even President Ronald Reagan, sadly a free trader even threatened nations to end trade deals that is not in our interest, and even imposed a Tariff on Japan to save Harley Davidson, even free trade Senator Daniel Webster even came around on Tariffs with the the Tariff Act of 1824. American was built on being ecomically Independent, not dependent on the rest of the world, the war of 1812, and the blockade during the Revolutionary war taught us those lessons on being spent, being spent on future foes like Mexico, and China will hurt us long term.
The modern GOP been taken over by Troutskite Neocons, Lifestyle Libertarians, and the Eastern Establishment, it resembles nothing of its glorious past. Sorry but I break with the modern GOP on Free Trade, deindustrialization, Globalization, the NAFTA, CAFTA, GATT/WTO, TPP, Consumerism(as a opposed to Production, and making things, while competing domestically with low taxes)
I agree that our a lot of our Citizens sadly have a Drug problem, a lot of the Lifestyle Libertarians, counter culture movement, Rock, & Gangsta Rap, Liberal Hollywood , the 60's hippie revolutionaries are to blame for glamorizing and popularizing Drug use to generations of Americans through Television, Music, Movies, and on College Campuses. However if anything is to be done a lot of the Democrats, and Lifestyle Libertarians all of a sudden cry about freedom, I believe a New just say no campaign is needed to patronize a drug free society, we need to raise excise taxes on legal Marijuana to pay for treatment, and rehab for drug users, we need to stop the flow of drugs coming into the country from places like Afghanistan, Pakistan, Mexico, Columbia, Peru, etc. We need to cooperate with the Philippines in their war on drugs campaign, we need a declaration of war against the Mexican Drug Cartels, and Mexican Prison Gangs here in America, and In Mexico to take them out, and destroy their supply routes, using special forces, Green Berets, the Militia, Special Old, Navy Seals, the Texas Rangers, etc. Backed by overwhelming Naval, and Air support, we also need zoning laws to not allow drug use, needle exchange programs, Marijuana shops, etc. near recreational parks, Day care centers, senior citizen centers, hospitals, Public and Private schools, clinics, businesses, Federal lands, etc. Still Mexico has some blame not just our people, with their corruption, and allowing these Cartels to send their filth drugs, and their dealers into our Country.
canada may not be big enough but other countries will trade with us, Breaking the sanctions on Russia will help with Trade with those folks, they crave American goods, we can trade with Belarus who been trying to balance their relations with Russia, and the west, we can finally start trading again with Egypt, now that Trump is on good terms with Al-SISI, Trump is now on good terms with Victor Orban in Hungray, trade with the Hungarians is good, trade with Central & Eastern Europe in general could replace Mexico, etc. It not A accept free trade with the Bad Hombres or die situation, most nations still look to American markets, and buy American goods, listen to American music, watch American music, but we must protect ourselves, or get surpassed by the cheap slave labor nations.
Another thing I forgot to mention is that most businesses that relocated to places like Mexico, Central America, South Korea, Japan, China,etc. Will realize if they see a 30% tariff on their goods (plus duties) , then it cheaper to do business in America, granted that the Corporate Income tax is reduced to below 10%, OSHA is relaxed to a certain degree, and Right to work legislation is allowed domestically to foster a good business environment, with the precondition they keep their business here.
