Also GDP, GDP PPP and every other economic benchmark is calculated using CID - constant US dollar; specifically to avoid skewing results due to fluctuating exchange rates.
> This swing is the main driver of this whole thing and means that yes, PPP is superior for looking at growth.
It is technically incorrect on every level. As GDP PPP fundamentally is unsuitable for calculating growth.
The GDP of Greece pre crash was $355B today it’s $219B, it’s GDP PPP pre-crash was $341B today it’s $389B if you think the Greek economy grew over that period or that today it’s a better place to live in with 11% unemployment and youth unemployment approaching 40% with the entire population having its wealth cut by nearly half than pre-2008 Greece then I have an island in the Aegean to sell you…
That is all.
What it may or may not say about Greece is utterly irrelevant because that's not what I was talking about.
If you want to say it's a more accurate model then you need to defend it more broadly.
