It appears you are correct. According to wikipedia, recycling is cheaper than landfilling.
But, that ignores the cost on the consumers of sorting their trash, and also ignores the environmental costs of landfilling.
I wonder if it also ignores federal subsidies.
I still oppose it because it is annoying, and costs too much in wasted utility of millions of citizens. Try hiring people to sort it at the landfill and see if it is still cheaper. Right now, all that work is done by us.
