Why were trusts declared illegal?

they were declared illegal because they tied in with monopolies. monopolists were starting to hurt businesses by charging too much money for things, thus driving down their competition as a side effect - reducing the tax and tariff revenue paid to Uncle Sam. Well, you just don't do that. If Uncle Sam can't have HIS cut, nobody can. So instead, the US Commerce department promotes competition so nobody can "corner" the market on something and cause artifical prices to prevail. and my social studies teacher told me that trusts and monopolies started to control the government too much.

my teacher and Yahoo answers :) hope this helps
