Raising awareness of the economic advantages of universal design

As the work in the field of Universal Design advances, more and more practical solutions to a myriad problems are presenting themselves. The technology now exists to bring products to market at a reasonable price that can be used by a larger number of people than ever before. With the expansion of the Internet and wireless telecommunications networks, this is particularly true. Properly presented huge amounts of information can now be used by the most diverse audience in history. Much of this is due to the implementation of Universal Design Principles in building accessible web sites. But there is a persistent feeling amongst some that this is enormously expensive. What can be done to help everyone understand that implementation of these principles will not only increase the size of the user population for any one product, but is the most economically feasible method for producing goods and services?
