All the discussion about who might take these jobs is largely moot if WYOMINGPILOT's previous statement is accurate:
"The Recruiting agency I just spoke with said EASA no longer allows anyone to fly on a validation license so you MUST have the EASA ATPL before starting employment." That would stop many of the willing in their tracks.
While I don't doubt they can find a US citizen or two (or more) already holding an EASA license, there's no data yet to indicate what their other quals or inclinations might be.
This issue needs more facts and time to see how it's going to shake out. So far, just the Blind Men and the Elephant. ;-))
