Funny, you should read Adam Smith's opinion of landlords:

or quoting from mises.org(!)
Smith was even less kindly to the role of landlords, where he recognized no economic function whatever that they might perform. In pungent passages, he writes that 'As soon as the land of any country has all become private property, the landlords like to reap where they never sowed and demand a rent even for its natural produce'. And again: 'as soon as the land becomes private property, the landlord demands a share of almost all the produce which the labourer can either raise or collect from it'.
