Well...while the intentions are there - with existing hard infrastructure - the biggest obstacles are the soft infrastructure, the institutions. Institutions are non-permitting when it comes to innovations to improve effectiveness and efficiency. Theoretically, we can discuss on their inability to reward innovators (in the form of patents etc)- while in addition in reality, gate-keeping is one of the obstacles of innovation. For example, individuals who own transport facilities (trucks etc) would be against the idea of adopting rail transportation to protect their purses.
Secondly, the sunk-cost fallacy of the individuals deter them from accepting innovative initiatives. The mentality of being comfortable with what they have learnt over time and the fear of being a novice in new initiatives deters individuals to push for the latter.
