EFF's Encrypt the Web project aims to fix that, and Let's Encrypt—a collaboration with Mozilla, the University of Michigan, Cisco, Akamai and many other sponsoring organizations—should be a huge step forward.
The larger barrier, though, is difficulty. Once someone has purchased a certificate, they need to install it on their website, a time consuming and error-prone process that requires significant technical skill, which is a cost in itself.
Not to mention it is annoying to renew your certificate every 90 days, which is the maximum lifetime. If you run your own server, you might want to run some beta software to automate the updates; if you are on shared hosting, or require stable and production-ready solutions, better stick to traditional SSL certificates.
