Brick Work
When volunteering with Habitat for Humanity I was told that there were no wheel barrows in Bangladesh. I hadn't realized it before, but I never saw one. Bricks were everywhere, but they were carried stacked on people's heads. H4H tried having wheelbarrows made, since they couldn't be bought, but they were of such poor quality that they only lasted a day. With so many available workers, wheelbarrows seem less important.
