The factories produced clothing for retailers including Walmart and Benetton, according to The New York Times.
"The apparel industry's relentless and blind pursuit of the lowest possible wages cannot be sustained over time, ethically or fiscally," Charney writes. "As labor and transportation costs increase worldwide, exploitation will not only be morally offensive and dated, it will not even be financially viable."
In an emailed statement to The Huffington Post he added "The truth of it, and it is important to be said, [is] that the clothes we wear do not have to be at the expense of the lives of others."
Using low cost workers in less developed parts of the world is not unique to the apparel industry. And this isn't the first factory disaster in recent months. Back in November, a factory fire killed 120 people, also in Bangladesh.
There's always outrage and recrimination after things like this happen, but it's too rarely sustained.
