>Meanwhile in the US I am getting 4.5% of a few high interest savings accounts I have open, I am not sure if these options are available to Europeans
They aren't. In my Euro area the highest interests on savings accounts I can find at banks is 2,5% and that's as a special offer for new customers.
We in Europe are being fleeced from all sides, while banks, energy, real estate, food companies are having their most profitable quarters ever. Something's gotta change.
