Answer to Question #48104 in Other Economics for Billy
A special interest group may be successful in getting a project approved even when the potential costs far outweigh the potential benefits because:
they are informed voters on their special interest and will reward politicians who support their interest. or
most other voters remain rationally ignorant of the issue; thus, their opinion of the politician remains unchanged. or
the cost a single, average taxpayer must pay is less than the cost they would incur if they were to protest the project. or
all of the above.
