There's actually a web site called CheatHouse! And it's a pay site!
And if there's one, there's probably many, especially seing how professional this one looks. I wonder how much money is earned every year on students paying for access to ready-cooked essays like this?
I wonder how many are dull or stressed enough to just copy such essays directly?
I wonder how long it takes on average from an essay is posted until it is familiar to every smart teacher in the US? They are not exactly hard to find, this page was right near the top of a simple google search, along with several similar sites (it seems nobody is interested in "robber barons" except teachers and students). Although admittedly this site claims it alone has over 100,000 essays and over 30 new essays added daily. It can't be easy for teachers to keep on top of that. Unless of course several students in a class cheat from the same source.
You know, just reading the first paragraphs of a couple of these essays, it strikes me how boring it must be most of the time to be a teacher and have to constantly read and grade generally-boring-and-unoriginal (it's hard to be original and why take chances with your grades?) essays on the same eternal subjects. Wow.
A lot of them - at least the better, more expensive companies - give out one-of-a-kind essays. Properly researched and original, there is no way to identify them as not the work of the student.
