Abstract: 무능한 낙수효과는 이슬이다. 
재대로 먹어보지도 못하고 사라진다. 
잠깐 존재하지만 금새 사라진다. 
존재는 하지만 혜택이 거의 없다. 
이슬이 비가 되어야 하는데 무능한 낙수효과들의 돈을 담는 그릇은 무한이 커서 넘쳐흐르지 않는다. 
다만 공기 중에 습기가 잠시 이슬이 되어 돈을 담는 그릇에서 한 방울씩 떨어지는 것처럼 보일 뿐이다. 
유능한 수도관교체효과는 필연이다. 
녹슨 수도관이 교체되어야 녹물이 사라지고 깨끗한 물이 막힘 없이 나온다. 
무능한 낙수효과를 기다리는 것보다 유능한 수도관교체효과가 낫다. 
무능이 망해야 새로운 유능의 자리가 생기는 것이다. 
낙수효과로 사는 무능 바로 사회의 암 덩어리인 것이다. 
망할 회사가 망해야 유능한 회사가 일어날 토대가 마련된다. 
무능한 이들이 운영하는 망해야 할 회사는 유능한 이들에게 그 시장가치대로 넘어가도록 해야 한다. 
이는 무능한 이들에게도 좋은 일이다. 그들의 재산이 증가하기 때문이다. 
무능이 유능으로 대체되는 시스템이야 말로 진정한 수도관교체효과이다. 
이를 통해 개인의 부도 증대되고 사회의 부도 증대된다. 
무능을 살리기 위한 낙수효과는 무능의 부만 증가시켜주고 사회의 부를 감소시킨다. 
무능은 유능을 싫어한다. 무능을 숨길 수 없기 때문이다. 시장원리는 무능에 돈을 투자하지 않으려 하지만 시장원리가 아닌 곳에서는 무능이 돈을 받는다. 무능을 제거하고 유능이 들어온 다음에 돈이 투자되어야 투자자들의 이익이 보장받을 수 있다. 회사도 지속 가능한 경영이 가능하다. 그렇지 않으면 사회의 부는 무능의 부를 증대시키는 수단이 될 뿐이다.
