A middle class person is similar to cheese in a sandwich.A sandwich will never taste good if there is no cheese and fillings in between the breads or buns. Same is the case with the economy, the middle class person is supposed to be the most juicy and tasty ingredient of the country who is stuck in between the rich and the poor.
If governemnt needs fund, it will impose a tax or raise prices of essential commodities to fill its exchequer and then distribute the same to the poor in form of subsidy and direct benefit transfer. If a rich needs money to do business he will go to the banks where the middle class deposits it all the savings and later on if the business fails, the company is wound up and the Directors flee the country, the ultimate loser is the middle class.
So, if there is no middle class then there is no taste to either the rich or the poor. The country will be like a sandwich served without fillings.
Although the observation is just a limited view and does not represent everything generally but some bitter experiences have compelled me to know the opinion of others too.
