The sentences that reflect that victory in the war depends on the participation of all civilians are:
"A free nation has the right to look to the leaders of business, of labor, and of agriculture to take the lead in stimulating effort, not among other groups but within their own groups."
"The best way of dealing with the few slackers or trouble makers in our midst is, first, to shame them by patriotic example, and, if that fails, to use the sovereignty of Government to save Government."
In these sentences we can see Roosevelt's intention to call out to every man in America, not only working man, but also business leaders. He also bids his citizens to lead by example, so those who are unwilling to participate may change their minds.

Beloved today, but at the time was hated by many.
