No good… it was a photocopied handout, and I read it about 15 years ago and 2000 miles away. 
Any ideas on the paper bag poem/prose? I remember the feelings and imagery that I got from it vividly, but nothing more about it than what I wrote in the OP.
That would be
A DAY AT THE LOTTERY FAIR
by Frederik Pohl (I think that the title)
The answer to the poster’s original question about the amusement park for population control is
“The Carnival” by Michael Fedo.
reference: The Carnival (short story) - Wikipedia
similar to Pohl’s “A Day at the Lottery Fair” but different stories.
Cheers.
And it only had to wait until the OP was banned. wonder if he’ll ever read it.
BTW, since the question has finally been answered, I’ll report the thread to get it closed.
Done. Although now I’m wondering about that poem. Maybe someone will find an answer in another nine years.
