This is inevitably going to involve my personal opinion - but ultimately my feeling is that the philosophical project has sort of crushed itself. The great philosophical successes of the Renaissance and Enlightenment led to the formalization of the scientific process. In turn, this led to rapid development in engineering and technology.
However, now we stand at a point where the amount of data collected and the inherent complexities of fields that have been developed over centuries are very obviously beyond the capacity of a single person to understand. I think that there was a hope that there would be simplistic answers at the heart of philosophy, answers which could easily be explained to others and which would lead to some ideal state for humanity. Religious structures often provide models of the universe that rest on (relatively) easily understood principles, and those religions which were excessively esoteric had faithful adherents, but often died out.
Unfortunately, it seems that no simple answers are in sight. The complexity of our understanding of the world seems to increase rapidly with no signs of slowing, and one an easily spend a lifetime becoming an expert in a once valued field that is suddenly irrelevant.
I see little that philosophy can do about this situation - a rational strategy for a person to improve the world around them is to learn as much as they can about the world, and then use whatever knowledge is obtained to rectify some problem or invent some new solution. Yet if one is to be a true authority on any subject, they must dedicate a significant portion of their life to it - and even then, they will still have a limited understanding of their chosen field of study, and at best a cursory understanding of the world outside of that field.
So say that the people as a whole see finance as a field that must be regulated, yet the world of finance has exploded in complexity since the invention of the computer. One must study the subject for years in order to even comprehend what is going on, and every day it continues to expand (I've heard algorithms now make trades in nanoseconds - a human mind can barely comprehend such a thing). How then can an individual (or even groups of individuals) have a strong enough understanding of finance to regulate it, as well as enough skills to craft legislation that will alleviate the situation and not create even worse problems? How can such a person make a case to voters when the subject is so dull and convoluted? Why would one pursue such a path when it is looked down upon by many and significant material rewards are within reach with this knowledge?
Thus one of the most essential philosophical questions: how should we act in the world in order to improve it? is becoming more and more difficult to answer, as a natural outgrowth of the success of philosophy and science.
Ultimately, I think a good reaction to these difficulties is to think more locally - find a way to make a difference in the here and now and worry less about the disasters that are beyond our control. If you see that you are helping to manifest a positive environment around you in whatever capacity, and others around you agree, then it may be time to begin working on larger ranging issues.
