Nobody Knows Such Simple Reality of Economics.

If a business is producing useable products by using all resources from inside the country like raw materials, employee, capital etc whatever the business need, then never get lost for national income perspective even business get lost unless producing goods for usable. if producing goods are not for useable that time national income must be lost because of our raw material work value of employee etc. would be useless but if producing goods are usable and going to sale in the market then nothing is lost even business getting loss.  In that condition why business getting loss because their products are sold in the market below selling price than its cost price. Then who gets the benefit?  everybody may get the benefit from this business from customer to all other related people like an employee, raw materials suppliers loan providers etc. if we observe here deeply then we can find out that all money is still inside the country due to loss business other related people getting profits means no effect for the country national income because all producing goods are used. In that situation, loss of business must be compensated by the government because the government would collect more tax from those people who get benefit from this business. This simple fact of economics nobody has yet explained. Economists are busy to research about eatable rice. if you are hungry, you must make rice and eat but economists start to research about rice even rice have been made from a thousand years in the same way. People need product and service for run life so research should be focused on the scientific field. How to make a good product from every aspect. All economics-related research are worthless activities. Everything can be cleared using common sense then why should do research.
