I would disagree with Sowell on this. The reason the millions of individuals, firms and families do better than central planners is the individuals, firms and familiers are much greater experts on their tastes, income and profits than any central planner could possibly be.
So the experts are right in this case, it is more matter of confusing who the experts are. Central planners can not possibly be more expert in your life or firm than you are.
The goal of central planning is not to provide the individual with what they want.
On the contrary, it is to force choices onto the individual that the planners deem to be superior to the choices that the individual would make if free to do so.
