“Spain doesn’t have 2 trillion dollars to get its economy back on track.”
Has Spain’s economy been on track anytime since 1700 or so?
Probably not but some bad economies have been better than others. In 2008 they essentially lost a generation as working age people left the country and, as things did get better, they didn't come back. After many years of population loss it started stabilizing and the kids were sticking around. Now it's heading for the toilet again.
