Paul Krugman puts the nail in the coffin of the "skills gap"argument by pointing to this piece:
Kudos to Adam Davidson for some much-needed mythbusting about the supposed skills shortage holding the US economy back. Whenever you see some business person quoted complaining about how he or she can’t find workers with the necessary skills, ask what wage they’re offering. Almost always, it turns out that what said business person really wants is highly (and expensively) educated workers at a manual-labor wage. No wonder they come up short.
