Brand purpose: thumbs up or down?

Elvis didn't want to be a singer. He wanted to changed music. Did he have purpose? Ahaha. I believe that great brands need purpose. What do you think? Do you agree with the following statements about brand purpose?

1.Business can do well by doing good.

2. Great products that are based on real problems that consumers really care about.

3. First it was product benefit, then it was emotional benefit, and now social benefit is new frontier for brands.

4. Purpose can reinvigorate and empower capitalism.

5. Purpose will make better brands, brighter companies and lasting legacies for all.

Will you give purpose the thumbs up, or the thumbs down?
