More victims of the war on drugs...
The sad part is how cheaply the lives of these young people, including the future school teachers of this part of Mexico, were thrown away. In a podunk place like Iguala, where literally every state and local was on the payroll with the cartels, the apparent desperation at having a drug-carrying bus discovered galvanized not just the police, not just the 27th Battalion, but EVERYBODY, to slaughter anybody they could find on a bus. They appear to have been more organized about this mass murder than they were about anything else in their sorry careers "protecting" the people of Mexico.
Every time I feel disgusted about the state of politics in the United States, I should remind myself of what Churchill said about our system: it's the worst, except for all the others.
It is like telling a friend who just got a great job that they shouldn't be happy because there are other people who won the lottery or had far greater success stories. (I did reverse it from negatives to positives.)
It's more akin to a friend who has a terrible job spending a few days working at a good job and realizing their job is terrible (to keep it reversed), or like a friend that has a good job but thinks it's terrible spending a few days actually working a terrible job and realizing how good theirs is (to keep the argument the same as AJ007 presented).
So using jobs, it is like having a job where you have to often pull 60 hours weeks and then having to spend a few days helping a friend pulling 80 hour weeks (with same compensation). Even then, the 60 hour weeks being the norm is a bad thing and saying that someone shouldn't feel bad about it doesn't make sense.
The switch was from bad/worse to good/better.
And to be clear, I don't think the cure for thinking that "(insert first world country) is absolutely terrible" is now good, just that it's relatively better than the initial assessment.
To get back to your original response, it's like telling your happy friend they shouldn't be absolutely content because yes, there are people out there that are doing better financially (assuming you are willing to equate financial success to happiness). It won't make them happier, but it will make their outlook more realistic (which isn't always a good thing). But again, reversing the statement like that doesn't preserve it's logical attributes. e.g. If A implies B, you can't infer that B implies A..
This is what gets me about Mexico. There's simply no value to human life there anymore. It's so depressing seeing what's happening there. The corruption is so deep and so ingrained in their culture, I can't even fathom how they will ever get better.
You don't need to hide coke in school buses without the war on drugs. The U.S. government is directly responsible for these and all drug war deaths.
Directly? That's a reach. Many factors lead to a situation like this, and US policy may have contributed, but don't diminish the part played by the people actually murdering and ordering the murdering.
