well, if you want an idea of how far that quotation is from marx on related questions, go here:
http://marx.eserver.org/1887-the.hou...ourgeoisie.txt
or you could look at the sections on the colonies from capital, vol. 1 of which came out in 1867.
i couldn't find anything like the quote in capital, but i don't have time at the moment to do too much searching--there's a searchable complete text at the same website, above.
"the irish question" deals in passing with rents, but it's mostly notes.
