Industrial incentives, 1947, Manos a la Obra

In May 1947 the legislature approved the Industrial Incentives Act, Law number 346, with a technical follow-up the following year. Qualifying manufacturers received a temporary exemption from the insular income tax, the property tax, and certain municipal levies. The program's popular name is Manos a la Obra and, in English, Operation Bootstrap. It is an industrialization-by-tax-exemption policy. It is not an agricultural settlement scheme, nor a mainland New Deal alphabet agency wearing an island hat.

Bootstrap begins here: industrial tax exemption, 1947. The Land Law is 1941. Do not swap them.

The bet was simple. Puerto Rico was already outside the federal income tax. Add local exemption, cheap labor, and tariff-free access to the mainland market, and mainland firms would build plants. Teodoro Moscoso's Fomento sold that bet. Luis Muñoz Marín's party supplied the legislature. The first plants were labor-intensive: clothing, food, light assembly. Later plants would be heavier. The first fact is the exemption itself.

Agriculture paid the labor bill. Hands that had cut cane or picked coffee took factory shifts. That was the point. A development program that leaves everyone in the countryside has failed its own name. Later critics treated rural emptying as a betrayal. The statute's text is about new industry. If you want farm results, read the Census of Agriculture after 1950, not the incentives law as if it were a hidden agrarian code.

The federal section 936 would later fuel a second generation of plants and then, by 2006, pull the fuel away. That is a later lesson. 1947 is the local exemption and the slogan. Manos a la Obra is a straight phrase. It does not mean hands back to the farm.

Spanish: Manos a la Obra, hands to work. Fomento, the development apparatus, is the next record.

Keep the moral heat if you need it, but keep it after the date. A tax holiday for factories is a concrete instrument. It can be judged by plants opened, wages paid, and farms lost. It cannot be judged as if it were the Land Law or the Jones Act. Those have their own entries. This one has May 1947.
