> The fed is trying to raise unemployment, not lower
No, the Fed is trying to lower aggregate consumer demand to rein in the growth in consumer prices. If it could acheive that entirely by adversely impacting availability and cost of credit while unemployment kept dropping, that would be ideal, given the other side of its dual mandate.
It accepts as a natural consequence that unemployment will likely need to go up to acheive its goals on inflation, but raising unemployment is not a goal.
