Now let's get this sorted out.PPP is more or less taking a basket of products and services and comparing their aggregate costs in different countries.It seems like a fine way of measurement until two things crop out-
1-
Decline in quality: While a meal,taxi,massage etc etc may cost you less due to the low labour costs in third world countries,there is a sharp drop in quality to make up for the "cheapness".As soon as you start to set the bar higher the costs shoot up and there is no price advantage left to speak of.In some cases,the products and services may get far more expensive.So when one balances the reduced cost but lack in qulaity,the PPP benchmark is inherently flawed as it fails to account for the difference in quality of same product across different countries.
2-
PPP is useless for purchase of manufactured products and services requiring expensive infra and highly skilled labour: The main reason why countries score higher in PPP is because the lower labour costs drag down the price of many products and services at a disadvantage mentioned above.But as soon as it is a service or product requiring highly trained labour and extensive resources to produce,the PPP advantage goes out the window.In many ways,the lack of the mentioned two things in third world countries even makes products and services far more expensive than the developed world.So the PPP advantage is mainly for basic needs like food,clothing and untrained and unskilled labour.
Case in point-manufactured goods and their costs in India versus those imported from China.A classic case is the Indian toy industry.Toys made in India are of an inferior quality and more expensive as compared to ones imported from PRC even after the costs of shipping and paying sky high customs and excise.The Chinese toys are of a superior build and more effective pricing.Same case for almost every other service or product requiring highly skilled labour and infra.
BTW-If US and Pakistan were considered two poles,China would be the middle ( for now).India is right there with Pakistan a snail's pace ahead but more or less the same.
I see and so does everyone how carefully you avoided a very simple question as it blows several holes in your facetious arguments.
"So let me get this-If I buy a laptop for 1500 dollars in US,in India I can buy it for as low as 500 dollars because of PPP advantage?
"
Let me come at you another way.Say a gallon of gasoline costs $3 dollars in US.Can I buy the same quantity in India for $1.Since you know PPP??
