My worry with your argument (if I'm following correctly) is why should we compare/base US immigration policy on the policy of other nations? If we accept that US policy is more favorable than others, is it purely acceptable to meet the lowest bar? I'd argue we should always, in all facets of policy and life, be actively working to raise the bar.
