No. The per-capita GDP for Portugal, Greece, and other small European countries are all distorted.
These countries use the common Euro currency. Additionally, these small countries receive subsidies from the central European government.
By sharing a hard currency with Germany (via the Euro) and receiving "transfer payments" from the European Union, these small countries have an artificially-inflated nominal GDP.
When it looked like the EU would no longer support Greece, the Greek bonds started collapsing.
If Portugal and Greece were forced to use their own currencies and DID NOT receive transfer payments from the European Union, their nominal GDP would be a fraction of what it is today.
Norway is an exception. It is a petrol state and exports vast amounts of oil from the North Sea.
Thus, the current Portuguese and Greek nominal GDPs are a reflection of SHARING the Euro currency and receiving substantial transfer payments from the European Union. It is not a reflection of Portugal's or Greek's own national merit as economies.
