G. stanley hall believed that development is controlled primarily by factors.

By purchasing $40 dollar sweater you will indirectly support a foreign industry, which earns its money by selling bulk items to its client, the well-known name brand. However, the clothing industry in Southeast Asia has a history of damaging the environment by pouring highly toxic residuals to nearby water streams.  On the other hand, by purchasing the $70 dollar sweater from the woman a few towns away, you will be directly benefiting her as there are no intermediaries between the customer and the producer. You will also be benefiting the women's suppliers of materials she needed to manufacture the sweater. Nevertheless, you will be incurring in excess of $30 in comparisson to the first option.
