The love of money, coupled with the perception of lacking enough of it, can lead to evil. Or it can lead to hard work. If you have enough money for you, it's not going to be the root of any evil.
Some people can be rich and still want more. Some people can be relatively poor and be fine.
The root of evil is greed and envy. It's not money or the love of it .
But it's false to say that love or lack of money is the root of all evil.
