There are multiple problems with your statement. First, what is a &quot;reasonable age&quot;? This subjectiveness obviously sets up a ratchet of earlier and earlier.<p>Second, who stays at a job for years on end today?<p>Third, you could say this about pretty much any group. Why hire a young woman who is just going to get knocked up and quit? (Seriously, this is&#x2F;was the argument against hiring young women.)
