why is it that while a blind person needs to use money there is no way for that person to read it?

            10 million blind and visually impaired people live in the United States.  Coins are the United States currency that are accessible for the blind without someone sighted reading the amount to them.    President bush along with the congress has been discussing a plan to make currency accessible for the blind, the provisions are as follows:    Money will be reprinted to where all bills are a different size, also bills will be made with each displaying a different color. Simply put this plan is not only costly and time consuming but the color change really has no bearing on accessibility to the blind. 

a better solution would be to braille the corner of the bills with the correct ammount.  this would giev the blind people in America the dignity they diserve.  i personanly hate asking somone to read for me.  while programs exsit to read my computer screen ther isnt anything that will read my money but anouter person in lin. this has proved to be problamaitc.  when i ask somone to read money at the store it seem a comon occurance that money turns up missing when i have my friend tell menwhat is lefe later. becuase i know what i have i just cant read the bills.

do you think there should be braille on the corners of money so blind people could read them
