I read elsewhere that in the US 50% of consumer spending is done by 10% of the population. (No figures for UK or Canada). Would this have implications for the driver of inflation?

@ChrisMayLA6 This is the case not only in UK. Most likely all over EU or even globally. Since Euro crisis and all that, wages basicly have stopped rising when inflation rate of living is considered. Only profits of big enterprises went sky high. The abyss between rich and poor became enormous.
But poor people cannot consume a lot. They can only by the absolute neccessary to survive, if at all. So inland markets decrease, economy goes down. If this is global, there is also decrease in exporrts.
