"我开始越来越积极参与移民改革，因为这是对生命的浪费，对潜力的浪费，对我们国家而言，不利用我们培养的人力资本——致力于改善整个社会，实在是太浪费了。"

Simplified Meaning:

The person who says this is talking about how important it is to support immigration reform because it helps everyone, not just immigrants. They believe that when immigrants are given opportunities, they can contribute greatly to society. For example, think of a smart student from another country who wants to study and work hard in the U.S. If they are allowed to stay, they might become a doctor, teacher, or engineer who helps lots of people. If they are not allowed to stay, their skills go to waste, and everyone loses out on what they could have offered. The person sees immigration reform as a way to unlock this potential, making the whole country better and stronger. By supporting policies that allow these talented people to contribute, we can all benefit from their hard work and dedication.
