>>49947752>You're just using nominal because it makes Britain seem better.No I'm not. Your problem is you don't understand the definition of GDP.
GDP is the MONETARY VALUE of goods and services produced in a country in a given year. Nominal GDP is this pure value in US dollars. PPP is distorted to account for cost of living (which doesn't matter at the national level, only at the individual level).
Your frankly pathetic argument is that exchange rates can change quickly therefore they don't matter. This is blatantly bullshit. Currencies get weaker or stronger for a reason, it's not random. The Euro collapsed because of weakness in the Eurozone, the Rouble collapsed because of the oil price crash. It is not random it reflects the health of underlying economies.
You are latching onto the PPP measure because you're that mentally-unstable German/Russiaboo and this is the last thing you have. The fact is that GDP PPP only cares about the domestic market, GDP is the monetary VALUE of what is produced, and if we're looking at countries as a whole, we want a true international comparison not the country with the cheapest Big Mac.
