Government leaders in Caldwell County didn't complete an economic study before agreeing to some 250 million dollars in tax breaks for Google. Local officials ran a computer analysis that determined a state job-creation grant of almost five million dollars would generate more than 45 million dollars in state revenue over 12 years. But they didn't study whether committing to three decades of tax breaks made economic sense. Google plans to build a 600 million dollar data center near Lenoir. The facility will create as many as 210 jobs. Records show that city and county tax breaks given to Google amount to 165 million dollars over 30 years. That's in addition to state tax breaks and incentives totaling 94 million dollars. The incentives package is among the richest in state history.
