Americans provide energy security to Europe at a cheap price. The Europeans should then pay back Americans for the value they have been receiving for free, and at the expense of Americans. There are more Europeans than Americans. How about each American receives $500 per month from Europe?
$500 per month per capita would be just a symbolic number, as a fair price could be much higher than $500.
