I've been listening to some fascinating podcasts on my morning runs the past few months...many featuring scientists. No matter if the subject is sugar or space travel, the one thing I've learned, and am trying to apply to my daily life, is that they always question EVERYTHING. Instead of taking 'facts' as 'facts', they investigate how those 'facts' were defined.
As an example, people used to think sugar was only a problem for poor people. But upon further investigation, when those studies were done, the wealthy often had in-home health care, which completely removed them from samples used to generate statistics, thus skewing data that guided studies for years to come.
My point: No matter the side of the debate we're on, we should really strive to get to the essence of the question. We're often not even fighting over decisions that are actually addressing the root of an issue.
This guy makes a VERY valid point in regards to immigration. It's not about how many people the US can take in every year, but more about how many people choose to stay behind, and try to improve their own communities and the lives around them. This will be way more impactful than our ability to take in 1m, 2m, or even 5m new people per year. With this knowledge, what do we do to make a real difference? Build schools in other countries? Support business development and encourage trade with 'poor' countries? Interested in your respectful discussion on this.
