In the middle of a blog post on human trafficking, it's claimed:
Another way to be involved with this issue is to help prevent boys and girls from being trafficked in the first place. Many of the trafficked children come from and through the Golden Triangle area of Myanmar, Cambodia, Laos, and Thailand. One of the at-risk groups are the Akha tribe, non-Thai residents who live in villages throughout the mountains of this region. The Akha children who finish the fifth-grade in local schools can only go on to middle-school if they have the mandatory school uniforms. Since the families generally do not have the funds to purchase the uniforms, the children, out of school and with nothing to do, are susceptible to being lured by traffickers with the promise of work in the ciy.
with text afterwards mentioning a charity that's raising funds to purchase uniforms.
Do people end up missing out on school for want of a uniform?
I'm somewhat suspicious of the source - I suspect that a charity could be creating an overly-simplified explanation for what's going wrong so that they can raise funds.
The claim being made is even more extraordinary considering what can happen to people who aren't allowed to attend school.
