Yes, it is fair to call Dolly Parton the modern, country Mother Theresa. In addition to Ms. Parton pledging to help Tennesseans affected by the wildfires, she also continues to employ thousands of her neighbors in what is a traditionally impoverished area. Without Dolly's help and support, the region would be much worse off.
She is in that she is a popular, famous person who is becoming known for doing good deeds. Of course one of the reasons why she is pledging money is because her home was one of the places affected by these fires. She is helping her friends and neighbors with this pledge.
Dolly Parton is not the modern country Mother Theresa. She is absolutely showing that she cares about what has happened in Tennessee, however if she were to be called a Mother Theresa, she would not only be helping Tennessee, she would be helping people all over the country and the world. While I think it is good to find someone doing great things for the people of this tragedy, I would not compare her to Mother Theresa.
No, Dolly Parton is not the modern country Mother Theresa. She is a good person with a lot of money who chooses to use it for good. She should be admired for her choices, but not compared to Mother Theresa, a poor woman who chose to spend her life helping the poor and unwanted people of India.
