CMV: Copywrites should only be valid for 20 years like patents

It is unjust that creators of copyrightable works are entitled to legal protection of their works for their lifetimes plus 70 years when patents only last 20 years (21 if you include the provisional 1 year period). Both types require creativity, effort, and resources but the amount of resources dedicated to the creation of ANY copyrighted work are inconsequential compared to what it cost someone to create some types of patented inventions.  Tens of billions can be spent on a single patented idea and yet someone is only entitled to benefit from this investment for 20 years while someone who writes down a story is entitled to benefit from it at the very minimum 3 ½ times longer. Furthermore, I would argue that not do patented things cost powers of magnitude more than copyrighted works as a whole those things that are patented have a much larger and more important impact on the lives and happiness of the world population than anything copyrighted as well. I love my copyrighted works as much as anyone but I would rather be alive (due to patented medicine and other quality of life inventions) then read a great book, listen to the  greatest song, or watch the most amazing movie.

So can anyone convince me that someone that creates a copyrighted work deserves to be entitled to be rewarded for their product for so much longer than someone who invents something.

Edit 2 ----

Just to clarify the argument is not that patents should last longer rather that if someone creates something they deserve the same protections for the same time period no matter if it a product or a song.

Edit ----

Since the point of patents having a bigger benefit then copyrights has been brought up multiple times I wanted to add some questions for those arguments

If the benefits to society are the difference what about copyrighted works that have a huge impact of society? Also most patents don't have a big impact on society so why shouldn't they have the some protection as a book or song?

The copyright allows them to keep on creating.  From the first Harry Potter book being released until the last was 10 years.  JK Rowling made those characters, why should she have to give them up?  She is still creating material.  This is why.

Patents are granted for novel and non-obvious creations.  They advance their art.  The patents that make money are rare, but when they do it is because they meet a need.  The 20 years for the patent is a balance to incentivize the creation of new things and allowing it to go into the public domain so that others can improve it.

A copyrighted work does not meet a need other than, it is art and it should be enjoyed.
