I have in fact read those articles. I think it's fair to say that the manufacturing conditions of fakes can be (doesn't have to be, but can be) abysmal. So are the manufacturing conditions of authentic Gap. And, probably, a lot of high-end pieces, too.
And so are the manufacturing conditions of illegal drugs when they're illegal -- eg, imported/dealt marijuana and cocaine in the US. Now, I am not a pot smoker but I have actually helped to trim plants - in Oregon, for a legal medicinal grower- and we laborers were lovely, articulate, unabused adults. (Though I wasn't paid... hmm?

) That's what legalization does - it makes things unseedy. It lifts them into the light. The marijuana trade has taken many, many lives, but alcohol once started the freakin' Mafia.
It's not the thing that causes violence/terrorism: it's the fact that it's illegal.
Which is to say: the prosecution of counterfeit luxury is what makes it harmful to laborers. And actually it's what makes fakes so expensive (yes, expensive!) for their quality.
The fact that I can buy a fake LV for $200-300 implies I could buy a no-name bag of LV quality for under $100 in a world without as much (1) prosecution, and (2) demand.
(Counterfeit luxury, to me, is a completely different issue than counterfeit food and medicine. So is passing off a counterfeit to a consumer vs a consumer passing one off to the "world".)
To be clear, I don't think we should buy fakes. I also don't think we
should buy luxury fashion when we could use that cash to help the poor or to build schools or to cure cancer reach Mars - take your pick. And should we even still be slaughtering animals to stack their corpses up in our closets? ... well, now that I put it that way... Luxury
is hedonistic and materialistic and self-absorbed. I don't mean that people who buy it are - but the thing itself is; there's not a lot of ethical rightness to luxury as a use of money, to begin with. A bit of hedonism is right in life. But getting up on our high horse about it... not so much.
Because isn't the most ethical thing we can do to prevent counterfeiting just... stop buying luxury brands? No more logo obsessions. Celebrate indie designers and craftsmanship. Buy local. Buy bespoke. Buy brands who emphasize relevant quality over branding (eg, indestructibleTumi luggage instead of LV). Many of the wealthy (especially the 'old' wealthy and the hypereducated) do this already. Luxury houses even offer it as a service to those willing to pay... but go with a small workshop and you'll get that kind of service at a fraction of the cost.
Others have said that we need to ask (ourselves) why people (we) buy luxury, not why "they" buy fake luxury. The consensus - "status." I agree with it. People think fakes give them status for the same misguided reason they think real bags give them status. That misdirection earns fashion houses billions a year.
-- enough from me on this. I was a social theory student in college and studied a great deal about marketing and brands, so this is my favorite topic for rumination. The disclaimer: I've never intentionally purchased fakes though one's been foisted on me more than one occasion... I don't smoke pot... I don't think you're evil to carry leather although I do think it's morally problematic, because I know we all do morally problematic things, and obviously I too carry leather.
