The major difference is<p>(1) The laws are designed to eliminate choice and freedom to pursue other jobs for the people being placed.<p>(2) &quot;Staffer&quot; company is able to take their 50% or more cut from their salary for entire <i>decade</i> or more every single month.<p>Imagine if you were running staffer company with this business model where law says that workers can&#x27;t leave the job you placed them and you get to pocket major part of <i>their</i> income for decade or more.<p>Technically sure they can leave your employment but practically they can&#x27;t because they still get paid bit better than their home country although much less than prevalent wages in US even after staffer takes his 50% cut.
