Poverty is a such a large and difficult problem. Someone's knee jerk reaction may be to "ZOMG, shut down the factory!" But the factory is providing a _relatively_ better environment than what may other alternatives may provide, such as prostitution.
Part of the problem is that these kids do not need to work; if you look at unemployment levels, it is not like Bangladesh is so poor that kids have to work. According to the CIA world Facebook (iOS spelling correction strikes again): "about 40% of the population is underemployed; many participants in the labor force work only a few hours a week, at low wages" (https://www.cia.gov/library/publications/the-world-factbook/...)
Poor grown-ups could do this work, but factories do not want to employ them because they work slower (possibly because they are somewhat disabled after years working as kids; at 80 hours a week without holidays, these kids will have worked more hours by the time they are 25 than a blue collar worker in the rich parts of the world does in his career) and because they are harder to control (and that would get harder once a generation sends its kids to school)
Also, it is not like Bangladesh is full of opportunities for educated people. Whatever you do, it remains a very densely populated river delta with few natural resources (they have oil and gas, but are net importers already).
The poor struggle. Daily.
In that struggle a truth emerges: Struggle is all you've known, it's what you knew yesterday and it is what you will know tomorrow.
For the poor struggle, hardship and despair dull the senses and the reality of the present stretches out before them. There is no future, there is just more of the present forever and ever.
What I feel those with privilege cannot comprehend is that words like aspiration, phrases like social mobility, are so alien that they are meaningless. If you're aware enough to have been angry, you're probably also aware enough to realise the stupidity of throwing yourself against the tide of the world. And so you accept and endure.
You can provide information but without hope and belief that change is possible to their lives, and that the struggle can be overcome, information is worthless. Food and shelter for a day are the only things you can offer of value.
But accepting your argument, I cannot give in to nihilism. Take the children out of the factories, put them in school, build libraries, train teachers, and wait twenty years to see a vast difference.
If you are a military dictatorship that uses your twenty years to educate the country and drag it by the bootstraps into the global upwards pastures, you may retire with your ill gotten gains on a beach somewhere with our thanks. Get rich and change nothing I want you hunted down with dogs.
(For example I see the biofabrication of meat as a technical solution to the awful statistic that cows in Europe recieve a daily subsidy of two dollars while around 1 billion humans globally live on 1 dollar a day)
