청년실업 해결? 말도 안되는 소리

대학교내에 총학생회 선거가 한창이라, 각 후보들의 선거 운동이 치열하게 벌어지고 있다.

그 중 재미난 공약중에 하나는 바로

" 청 년 실 업 해 결 "

참으로 굉장한 공약이 아닐 수 없다. 이것이 해결된다면야. 아마 대통령 선거도 나가도 될 듯..


뭐 아무튼.. 지금은 정보화 시대다. 블루칼라, 화이트칼라 를 가르는 그런 산업화 시대는 이미 지난 지 오래라는 소리이다.

게다가 대한민국 뿐 아니라, 미국, 일본 등 다른 나라도 마찬가지이다.

산업화 시대에서는 일자리 창출이 어려운 일이 아니었다. 건물을 짓거나, 공장을 지어서 인부를 쓰거나 하는 노동 집중형 

사업을 벌리기만 하면, 자연스레 일자리 창출이 되는 것이었다.


하지만, 정보화 시대는 다르다. 100사람이 할 수 있는 일을 10사람이 충분히 할 수 있는 시대라는 것이다.

게다가 산업 현장에서는 로봇, 기계가공장비 등을 이용한 곳이 늘어나고 있으니, 사람이 일할 곳이 점점 줄어 든다.

한가지 생각해 보자. 일례로 회사 사장이 하는 일은 수입을 최대화 하거나, 지출을 최소화 하여, 이윤을 창출하는 일이다.

그렇다면, 자본주의 시장에서 회사 사장은 다음과 같은 문제에 맞닥뜨리게 된다.

10명이 할 수 있는 일을 100명을 고용해서 할 것인가?

24시간 아무 불평없이 돌아가는 로봇이 할 수 있는 사람을 고용해서 할 것인가?

내가 사장이라면, 봉사의 목적을 가지고 있지 않는 한, 사람을 고용하는 것은 굉장히 이윤 창출에 반대되는 일이기 때문에,

일자리를 줄일 것이다.

간단한 예를 들어 보아도, 정보화 시대에서는 일자리가 점점 줄어 들 수 밖에 없다.


게다가 정보화 시대에서 교육이라는 것이 모든 사람들에게 굉장히 평등하게 적용 되기 때문에

사람들의 지적 수준은 산업화 시대에 비해 높아질수 밖에 없다.

그에 따라, 일자리의 눈높이도 덩달아 올라가,


실업률은 올라 갈 수 밖에 없고,

실업자도 늘 수 밖에 없는 사실이다.



이런 본질적인 원인을 보지 않고, 무작정 청년실업을 해결하겠다? 

정부 쪽에서 말하는 거야, 그런 대로 의미가 있는 말이지만,
