I believe that is probably true.  But that still doesn't solve the issue of seasonal employment.  Everyone gets so up in arms about outsiders coming to work here in the summer (and business owners hiring those people instead of locals), but the reality is that it's just not practical for most Alaskans to work for just a small part of the year unless it's in a Davis-Bacon wage job or something similar.  ADN did a great article on the J-1 program last year that presents both sides fairly, the link to it is in the article above.
