Precisely, we will never get back what we give up today, IF, a big IF, the company doesn't declare bankruptcy. I believe all of the B3 will declare. It's been planned. That will break the UAW and all those dollars will roll into the pockets of do nothing salary.
Remember Folks, these concessions only amount to a cost savings for the company of $1.6bil for 2 and a half years...(note, proper ellipsis), a drop in the bucket, a way to fund the "set aside" salary bonuses and payout scheduled for 2010. Yeppers, my Blue Collar friends, our White Collar overseers will be cleaning out our piggy banks while our gubment gives the company tax breaks to employ Iraqi refugees for $5 an hour. (A tad more "history repeating" for you to digest.)
In short; Labor will always take it sideways on the ingress. There is always someone more needy willing to do more for less and your tax bill will still be due April 15th.
God Bless America!
