I will do a video about it, but I think overthinking this tends to get some people a bit confused. When saying the value of the dollar increasing actually benefits Mexicans in Mexico, that is. It’s easy to look at it from just the US perspective, however it’s normally an incorrect and biased view. 
Let’s look at a few points: 

   1. Legal, (“because they were born there”) and Illegal (“that came over to work and send money back to their families”) are not the only status of Mexicans in the U.S. There are many in America that are legal because they became a citizen and are naturalized. Even if they never sent a dollar to Mexico, they are just as legal as you. There are many reasons and many statuses of people from other countries in the US.  

2. The US dollar rate going up does not necessarily have a good affect on Mexicans. Not as a whole. It only has an affect on the Mexican peso if exchanged. Everyone in Mexico doesn’t have someone to send them American dollars, so their life is only governed by the Peso, no matter what its value is. When affecting a US based company in Mexico, it then effects the individual Many could care less what the value of the American dollar is when they only get paid in Pesos and they pay their bills in pesos and attend to their families needs with pesos.  

3. If it does affect a U.S. based company, it normally never affects the individual people working there. That’s because the company may be making more money but they still pay the employees at the same low salary and in pesos. The prices of things around him/her may be increasing while he value of the peso has been decreasing. Yet that person still has to pay for their home, cars, etc out of their same low pay. Basically, things are costing more but they haven’t got paid any more. 

I fail to see how any of this is a “benefit” to citizens of Mexico.  

When attempting to live in another country, you must have the attitude of adjustment and adaptation. You must be willing to adapt to the new countries ways and standards of living and not expect them to adapt to yours.  

When someone is sharing information always consider the source.  If the basis of the information about Mexico is from U.S. News sources, be leery.  U.S. News is not nearly correct as even a summary for the entire Mexico.  It’s so easy for someone to give you what they think you want to hear just to get more views.  

There is a such thing a “click bait”.   This is the online way of stores doing rush based advertising.  You know, the “hurry, sale ends tomorrow” or even “entire store 75% off” (with small print saying “selections may vary”).   Typically someone posts a title of an article or video to be one that excites outrage, dismay, excitement, fear, etc just to get you to click on it.  When you see the video or read the article, it’s nothing about that topic or is without merit.  

I saw something that made me realize this is even being done and targeted towards those looking for information about Mexico. People have been seeing this source as a good source of info when it comes to learning about Mexico  and that’s disheartening because there are so many good sources of the great sights, food, fun and culture of Mexico.  Beware of anyone using scare tactics and constantly referring to the drug cartels when speaking of Mexico. This is just someone wanting to use fear as a way to get more views.   We need to insist that these sources be more pure and relevant to your own life, cause, situation or interest.  Just as in your country you may have no involvement with drug gangsters,  you don’t have to be involved with drug cartels of Mexico.  Do they exist? Yes. Do they kill over drugs or territory?  Yes.  Will their existence affect you walking across the street to the store?  Well, are you looking to score drugs?  Do you live in a well known gang and drug area?  If not it’s likely you will ever see or have any involvement with them.  They normally stay in their places, and mind their business.  

If your source of info, lives in a border town to the U.S.,  use that source as an opinion source only.  Their info can’t actually be viewed as credible regarding knowing what life is like in “the real Mexico”.  Life is quite different outside of border towns and tourist areas.  If you can still use the US dollar there, it’s not the best place for determining what life is like in Mexico.  Honestly life and culture can vary greatly from state to state.  

The U.S. News sources often distributes overly exaggerated news regarding what’s happening in Mexico.  The U.S. has an unprecedented amount of bombings, mass shootings and terrorist attacks.  Yet, you probably still consider yourself safe right?  Well, using that same logic.  Why wouldn’t you be safe in Mexico or any other country that’s not war torn?   When there was protesting, rioting, and looting in Chicago, Missouri and Virginia, did you feel safe in North Carolina, Colorado, and Washington?   Bad things can happen anywhere.  Please don’t let the ramblings of someone looking to ignite some fires for more views make you feel that afraid or anxious about visiting Mexico.  

Mexico is an entire country, not one city or state.  Wouldn’t you hate if those in other countries viewed the U.S. a horrible place solely based on bad news from Chicago’s south side?  
Consider your source.
