The morality if capitalism is a complex business. On the one hand it turns millions of poor people into what is essentially slave labour, but on the other hand it lifts millions of others out of poverty and into an unsustainable consumer lifestyle like we enjoy in the rich countries. Honda, the Japanese car maker, is trying its best to make this an even cloudier moral minefield by despite being an evil polluting car maker, inventing cool technology that could help the disabled to walk.
