Why company need experienced potential employees?

I believe some of you your interest suddenly shifted from being in an industry for many boring years to an industry that caught your eye,or an industry that is booming?SO WHAT DID YOU DO?You went to take a degree course,completed it and started hunting for job.

And then you realized that potential employers need specialized skills,and at least a 1 year experience.Not many employees are doing this,employing "fresh graduates".A diploma holder maybe,so overall the cost of employing a fresh graduate is much cheaper.

No experineced employess are better as they have the DRIVE of learning new things.Experienced ones maybe got bored of doing same thing more than a decade of their career,all they want is more pay,job hopping & hopping for that pay increase.

PLEASE,IT'S THE JOB OFEMPLOYERS TO TRAIN THE INEXPERIENCED POTENTIAL EMPLOYEES. COME ON,IS THE BUDGET COST TO HIGH?FACTORY ,OFFICE SPACE RENT TOO HIGH IS IT?

SO YOU EXPERIENCED WORKERS BETTER UPGRADE YOURSELF WITH NEW SKILLS,YOU THINK YOU CAN SIT IDLING AT THE COMFORT OF YOUR CAREER UNTIL YOU RETIRE?HAVE YOU GIVEN THOUGHT WHEN YOUR COMPANY WILL RETRENCH YOU?
