Musk is right to praise "Anyone – of any race, creed or nationality – who came to America and worked like hell to contribute to this country." But if he really believes it, he should stop supporting Trump-era GOP, whose ideology and agenda are totally inimical to these ideals.

Also, the harm caused by immigration restrictions is not limited to tech industry. They cause vast damage throughout the economy, to both migrants and natives. Migration restrictions undermine the economic liberty of natives more than any other policy.
