In the past few decades, we have witnessed what appears to be massive failure of experts on a number of fronts. In the media, people who certainly look like experts turn out to be con men... when well dressed "doctors" and "scientists" lie and trick people into making terrible choices, we grow suspicious. Anyone can pretend to know what they are doing, and blind trust of such people is a dangerous path to follow. Even the antivax people have what appears to a layman to be experts backing their side of the story.
Further, specifically in the areas of social policy, finance, and politics, the past decade or more seems to many to have been a disaster. Thousands of experts missed the financial disaster, and, from what the story looks like to many, bungled the recovery. The news that sells is all about disaster and the unexpected; things that experts failed to predict.
In is unsurprising, given these circumstances, that the title of expert is viewed not with blind respect, but with suspicion. If you claim to be an expert, then you are instantly placed in the same category as people who just want to exploit me for a quick buck.
I don't have a solution, but it is an explanation, and "trusting experts more" is not going to happen.
