No. It's the policy of central banks to keep currency stable.
Maybe. More to the point, what's the actual rate of price increase for oil. You say greater than 2-3% per year. Prove it.
That probably has more to do with the facts that:
1) Fiscal policy is more concerned with currency stability than price fixing,
2) Inflation is more concerned with currency stablility than price fixing,
3) Oil prices currently have less to do with currency stability than they do market forces. Two years ago that wasn't necessarily true: the initial run-up in oil prices to about $45/bbl or so was due more to low US interest rates than it was to supply and demand, as can easily be seen by comparisons to the euro at the time. Since then...oil's rising against both the euro and USD (and virtually any other currency you want to consider). And THAT is fundamentally non-inflationary, by definition.
In other words, your argument - once again - is horseshit, because you - once again - don't know what you're talking about.
If your particulary brand of stupidity is what passes for mental health these days...then I'm happy to be mentally ill.
