I am heaving a lot of problems with my back... sometimes I have so much pain I can not move from the bad... massage helps a little, but I can not go to work with such pain for several days...I've heard about magical effect of the pyramid, applying it under the bad you sleep on...in the morning you get up as a newborn...can anybody tell me if this is true or just another marketing trick?

Population of a nation is arranged according to their incomes. The highest earner is placed on top, the second one below him and so on. As we go down, there are more and more people having the same income. In other words to the bottom the structure has a broader base. Such an arrangement (figure or structure) is called 'economic pyramid'.
Then the pyramid is viewed as horizontal slices. The top slice containing p% of total population has q% of the total income in the country. Or the bottom p'% ha s only q'& of the total income of the nation. Normally, as an example it can be stated that top 5% earn 33% income and bottom 40% earn 11% income.

I understood your point of views.

What you are talking about is Uneven Distribution of Income. The problem of rich getting richer and the poor getting poorer prevails over the world.
Developmental issues need to be addressed.

Uneven distribution of wealth and income is one of the major problems. In this   multi dimensional forum this serious issue should be taken further.

Thank you
