Does this law mean "If you're going to drive drunk and kill someone, make sure it is not a rich person"?

New Tennessee law here that would for drunken drivers that kill an adult to pay child support to the dead person’s kids.

The interesting phrase is:
Courts would determine a reasonable amount of child support by considering the financial needs… and resources of the child or children, — and the standard of living the children are used to.

Seems like the upshot of this new law is: If you’re going to drive drunk and kill someone, make it a low income person because your child support will be lower. Sort of a strange incentive to target poor people.

Does this law make any sense?

Is it going to reduce drunk driving?
