`  == Modern mainstream economics ==  The modern mainstream economics section repeats itself a lot.  It opens with ``Mainstream economics begins with the premise that resources are scarce and that it is necessary to choose between competing alternatives.``  this is a reiteration of something found in the opening of the article - ``the science which studies human behaviour as a relationship between ends and scarce means which have alternative uses.``  Someone must really like repeating that though because later on in this section we see   ``Economics studies how individuals and societies seek to satisfy needs and wants through incentives, choices, and allocation of scarce resources.``  Then later in this section we see  ``neoclassical economics, which began to develop in the late 1800s and models choices made in the allocation of scarce resources.``  Then later in this section  ``It is sometimes referred to as the study of choice under conditions of scarcity.``  Then later in this section  ``Economics is a broad term given to the social science of how choices are made in face of limited resources.``  Then later in this section a word for word repetition of what was said in the opening -  ``the science which studies human behavior as a relationship between given ends and scarce means which have alternative uses``  Reading all of this I conclude that mainstream economics studies the relationship between given ends and scarce means which have alternative uses.  But I do not need to be told this six times (seven, if you count the opening).  This section also repeats itself in other ways.  I am removing redundancy from it.  `
