Q) Medicare Program Is the Medicare Program of the U.

Q) Medicare Program

Is the Medicare Program of the U.S. financially too costly in terms of expenditure growth that crowds out other government programs that are more beneficial or the private economy - too much taxes or debt?

What are the benefits and costs of funding other programs over this program? (This is allocation efficiency too.) 

Are there economic behavior effects that we want to alter of change because the program is too generous or not generous enough? 

Should it be redesigned to foster different behavior? Is redistribution working as society intends? In brief, what aspects need reform?

Please help! I need detailed answers in paragraphs please.
