The Congress finds that the supply of the Nation’s housing is not increasing rapidly enough to meet the national housing goal, established in the Housing Act of 1949 [42 U.S.C. 1441 et seq.], of the “realization as soon as feasible of the goal of a decent home and a suitable living environment for every American family”. The Congress reaffirms this national housing goal and determines that it can be substantially achieved within the next decade by the construction or rehabilitation of twenty-six million housing units, six million of these for low and moderate income families.
