The fact that benefits have costs means that those who create these benefits are tempting targets for accusations from those who know how to dramatize the costs. This means that the doers are constantly on the defensive when attacked by the talkers.
These attacks are especially effective in a society where most people have not been taught to weigh costs against benefits or to subject hot rhetoric to cold logic.
"Safety" issues are ideal for talkers because nothing is absolutely safe. A vaccine may save the lives of 10,000 children but, if five children die from the vaccine itself, that can set off loud denunciations of "corporate irresponsibility" and "greed" on the part of the companies that produced the vaccine.
Some people die from reactions to peanut butter. If the government banned every food from which some people can die, we would all die of starvation. If they banned every vaccine or drug from which people die, more people would die from diseases.
More than sloppy thinking and runaway rhetoric enables the talkers to harass the doers. The ever-growing jungle of laws and regulations provides a virtually unlimited number of grounds for lawsuits.
The talkers are in their natural habitat in courts where judges allow junk science to be used as evidence and juries are gullible enough to be impressed by glib and clever lawyers. The low cost of attacks and the high cost of defense tilts the system in favor of the talkers, especially since the talkers need pay no price for having made totally unfounded accusations.
Both the talkers and the doers know this. That is why the doers so often settle out of court, rather than be tied up in endless litigation. This is then taken as proof of guilt.
Anyone who wants to build anything can be hit with costly delays by environmental activists demanding environmental impact reports. It doesn't matter what the facts are, the talkers can always demand more information and object to the analysis.
All this takes time -- and more time adds to the costs of borrowed money, on which interest must be paid, no matter whether the building for which it was borrowed is being built or the machines and workers are idled while speculative complaints are being investigated by bureaucrats who are in no hurry.
Not only the legal system and the regulatory bureaucrats enable talkers to impose high costs on the doers at low costs to themselves. So does the talkers' ready access to the media.
