Congressional Budget Office says Trump’s immigration crackdown will shrink U.S. population faster than expected, a threat to inflation and GDP growth | Fortune

Can someone who believes that the current administration’s policy is sound/cogent/effective/etc… please explain why a declining population…I’m sorry, but let me correct that last part… why a more rapidly declining population is anything other than disastrous for our economy in specific and our nation in general???

Thanks in advance for the well thought out and specific response(s).
