Invisible hand VS Invisible inflation

Invisible hand VS invisible inflation is my title today. I assume everybody does not know what is invisible hand so i gonna tell you (again).

Invisible hand was probably the most significant Economic term created by Adam smith, the father of modern economics, in his book, An Inquiry into the Nature and Causes of the Wealth of Nations or sometime only known as Wealth of Nations (WON). A lot of economist try to describe the term in some very hard-to-understand way. So i will try to explain the term in the simplest way.

Every entity in the Economic such as you and me only care for ourselves and we shall choose the option of economy that benefited us the most. When every entity does that, it will create a market force called "INVISIBLE HAND" that will correct any unwanted or unhealthy economic problem such as inflation, unemployment, and so on.

In other word, we do not need regulator, the market which include everyone will correct ourselves. Example when prices of computer is high, we do not need government to implement price ceiling policy. We simply do not buy it (demand lowered) and hence the prices will drop again.

However, this is not the way our world is working. Every country on the planet do not like the idea and instead choose Keynesian theory of economic.

According to Keynesian, we need regulators such as government.

back to our topic, most of the country in the world recorded negative inflation rate, also known as deflation rate which mean continuously drop in the overall prices for the last few months.

Almost everyone blamed the Great Depression of 2007/8/9 as the sole reason it happened.

However, I DO NOT THINK SO......

We recorded deflation simply because we use Consumer Price Index (CPI) to measure the overall prices of all the products in the market.

Let me ask you a simple question: besides gasoline / petrol, anything around our everyday life became cheaper for the last 6 months?

Food? Cloth? public transport? bank charges? beauty products?

Anything became cheaper? Yes: price of properties, prices of commodities and prices of shares which have very small impact on the average life of a regular family.

So in other word, what we experiencing now is called deflationary asset prices and not deflationary goods / services prices.

For decades, leaders and regulators are telling us in order to achieve relatively high economic growth, we need to sacrifice moderate rate of inflation. Keynesian theory of economic really pinned into the mind of our leaders and regulators.

So according to Keynesian, US is the richest country in the world since US has the highest GDP figure in the world (25% of world GDP).

However US own 70% of total world debt. So, late John Maynard Keynes or any Keynesian Economist, can you explain this?
