The use of block grants, allowing states considerable leeway in how federal money is spent, was championed by president under the name new federalism.

President Richard NIxon

Explanation:

The President Nixon administration came up with the idea to decentralize power as well as some programs to the state governments of the USA to reduce the pressure on the Federal government in the wake of the continued unrest from the Vietnam war alongside unemployment, etc.

In decentralizing power and programs, the giving of block grants and aids to states ensured the reduction in the dependence of the economy on the federal government and as such states began to take care of problems within it.

Cheers.
