As they say, "Garbage in, garbage out."

I have watched with growing disgust the unimaginative, profit-mad and anti-child trash that the FCC's late, unlamented Mark Fowler so ruinously championed prior to taking leave of his fouled nest {"Saturday Morning Garbage," Style, June 15}. Garbage Pail Kids? That term applies equally aptly to Mr. Fowler's philosophical sympathizers and to the sick elves at CBS's children's programming division. It is obviously an office without a garbage pail of its own.

Isn't it pathetic enough that America's parents have abrogated their nurturing responsibilities to an electronic nanny, without its being a ninny as well? Or does anybody out there give a damn?

Deregulation has given us an increasingly incapacitated telephone system, irresponsible and unresponsive air carriers, predator banks and now, it seems, the stultification of our most precious resource, our children's imagination and sense of humanity, by stooges of the toy industry.

I have always thought that persons or organizations should exercise self-regulation and that control of any kind would be a direct infringement of our liberties. But after reading Tom Shales' "Saturday Morning Garbage" and having seen the Garbage Pail Kids cards on which the show is based, I am a proponent of restriction -- at least when a group can't seem to conform to the common bounds of good taste and decency.

Obviously CBS's desire to be first in the Saturday morning ratings has overcome its sense of taste. If CBS is no longer able to exercise restraint, I will boycott any product advertised by CBS on Saturday mornings, write the manufacturers informing them of this fact and ask that the FCC regulate children's programming. I encourage other parents to do the same.
