We are on the journey of systemic change. It requires two groups of people. There's the group who are willing to confront what is wrong, put everything on the table, and consider solutions that are very different and sometimes way outside the box. Then there's the people who cannot see that there is an issue or cannot visualize that there should be a different way. It is very hard to be the former when there are many of the latter around you.
Nowadays, if you have done something one way for a long time, it is probably time to take a look at what you are doing. Things don't have to be bad to need a change. They can be pretty effective and still be tweaked to uncover the true potential.
