&gt; a dollar invested in cleaners buys a greater fraction of lives than same dollar invested in doctors<p>the dollar equation is relative, i.e. &quot;in such a case&quot;. The balance point still ends up with doctors being payed more, and cleaners significantly less.<p>Plus, who guarantees that dollar cleaning improvement? Maybe all you&#x27;ll be doing is setting a precedent for higher pay - you need more to correlate with better cleaning. Maybe regular (independent) inspections &amp; testing?
