If preventative health care is really cost-effective, why doesn't Medicare cover it?

SOME THINGS MEDICARE DOES NOT COVER: NO routine PREVENTATIVE CARE, including physical exams NO DENTAL CARE. Medicare does not cover routine dental care or most dental procedures such as cleanings, fillings, tooth extractions or dentures. NO eye exams and eyeglasses NO hearing aids Co-pays = 20-50% of all charges, AFTER you pay a deductible Hospitalization Deductible = $1000+ SOURCE: EVERYWHERE

because medicare is broke and expanding medicare is to easy, they need to make a bunch of new government agencies to take control of our lives and put Americas foot in the door of Communism.
