Okay, just read it over. If they became a state they start getting "... an extra $20 billion a year in federal funds." However, "...Puerto Rican residents currently don’t pay federal income taxes, and companies doing business there don’t pay corporate taxes — two loopholes that would be closed if the island were made the 51st state." The question then arises, is the $20 billion a year in federal funds greater than the new federal taxes the residents and businesses would have to start sending to DC. I just did a crude estimation based on Mississippi, similar populations and economies. +/- $17 billion in federal taxes if my often off math is correct.
“Once Puerto Rico becomes a state, its fortunes could arc upward,” writes Reuters columnist Gregg Easterbrook, pointing out that Hawaii saw marked economic growth after it was made a state in 1959. Economic growth is not the same as a burden on taxpayer in the mainland.
Why does Puerto Rico want statehood, anyway?
