Since a few years ago, any EU or UK public funded research (which is most university research) must be published as open-access. It is a requirement of the funding. So this is already happening. However, it will need to be done by a greater proportion of the world to be effective.
The only problem is that the method of open access publishing is usually to pay a few grand to the publisher for the privilege.
