I disagree with much of Copeland's doctrine, including the prosperity Gospel. But...
God is not against wealth. In fact, many people use their wealth to further God's kingdom. The Bible even says that church congregations should financially support their elders with financial support so they can devote their time to prayer and the word of God more. Abraham was wealthy, Issac was wealthy Jacob was wealthy, Job was wealthy, Solomon was wealthy, Joseph was wealthy, Boaz was wealthy, Joseph of Arimathea was wealthy, and many more.
They used their wealth to serve God and weren't possessed by their possessions.
Wealth is not bad. Being wealthy is not bad. But loving wealth and serving wealth is bad.
