Real wealth is how much goods you can buy with your currency.I am fully behind indigenously produced weapons. A country like Turkey that has financial constraints and limited resources can not afford to waste money and valuable foreign currency in buying weapons.
But PPP is only good if you are not dependent on foreign imports. Therefore effects of high PPP based GDP is short lived.
Look at Turkeys exports and imports in the last year. 167 billion dollars exports and 210 billion dollars imports. The country lives on imported goods. The deficit has to be paid by tourism income and out of taxpayers‘ pockets or by borrowing.
Look at India ; Nominal GDP is 2.6 trillion dollars. But PPP adjusted GDP is 8.7 trillion dollars.
Look at Japan: Nominal GDP is 4.9 trillion dollars. But PPP adjusted GDP is 5.2 trillion dollars.
Do you really think India is richer than Japan?
Real sign of wealth is the measure of your Nominal GDP.
When the government can buy goods with national money they can print money and buy whatever they want.
That will effect the economy but won't stop the government from doing it.
