Advocates of comprehensive immigration reform give many reasons for their effort. They want to fix the nation’s “broken” immigration system. They want to secure the border. They want to bring 11 million illegal immigrants “out of the shadows.”

But there are other reasons that don’t receive as much attention. For example, during the recent Senate debate, reform supporters expressed hope that a new generation of immigrants would pay for the Baby Boomers’ golden years — and get the nation out of a huge fiscal jam.
