You&#x27;ve once again avoided giving even a qualitative answer as to what strain caused by immigration would look like.  A first step would be admitting that it&#x27;s even possible.<p>You&#x27;ve also made the mistake of thinking that just because you&#x27;ve found one problem that others must not exist.  We can have broken systems <i>and</i> problems caused by immagration.<p>10% ESL students in our public education system should qualify as a strain.  17% of California&#x27;s prisoners being born abroad should qualify as a strain.  Are these numbers not high enough for you?  If not, what does too high look like to you?
