Not so much. The Cotton states were rich. They had their own elites, who might have felt slighted sometimes by Yankees, but who certainly believed in their own superiority and asserted it when they could.
Very few Northerners "built their lives and values around technology." Most Northerners were farmers or were in businesses that didn't rely on anything that could be called High Tech.
Those who controlled cotton mills usually had little animosity towards Southerners. They needed their cotton. And people like Carnegie and Edison probably didn't give much thought at all to the South, except as another market for their products.
Don't make the mistake of thinking that the way things may be now reflects what was going on a century and a half ago.
