ยง 202. Congressional finding and declaration of policy
(a) The Congress finds that the existence, in industries engaged in commerce or in
the production of goods for commerce, of labor conditions detrimental to the
maintenance of the minimum standard of living necessary for health, efficiency, and
general well-being of workers
(1) causes commerce and the channels and instrumentalities of commerce to
be used to spread and perpetuate such labor conditions among the workers of
the several States;
(2) burdens commerce and the free flow of goods in commerce;
(3) constitutes an unfair method of competition in commerce;
(4) leads to labor disputes burdening and obstructing commerce and the free
flow of goods in commerce; and
(5) interferes with the orderly and fair marketing of goods in commerce. That
Congress further finds that the employment of persons in domestic service in
households affects commerce.
(b) It is declared to be the policy of this chapter, through the exercise by Congress
of its power to regulate commerce among the several States and with foreign
nations, to correct and as rapidly as practicable to eliminate the conditions above
referred to in such industries without substantially curtailing employment or earning
power.
