Workers at Cooper Tire in Texarkana seem ready to take a three-year wage freeze, pension concessions and higher health costs to keep the 1,400-worker plant open. Is it enough? Cooper is going to close one of four plants and its shakedown of workers and four states has produced an offer of a wage cut from Ohio workers and a $30 million direct payment — not a loan, auto union haters — from Mississippi. No word yet on how big a tribute Arkansas is willing to make.
