This link appears to be the same, in that it only concerns income tax.
Is it because nearly all of the population is in poverty, and surviving be subsistence farming?
Is it because most of the country's income comes from other sources, and only those making $1M or more have an income tax?
Those are two very different scenarios which lead to the same observation, so I can't see how you can draw a single perspective out of it.
