Who cares about this strawman "many places". We're talking about the US. Again: Why is it important to allow this illegal alien to stay in the country?
Do you also think deporting the 11m people here illegally would be good for society? Protip: it would be devastating.
It's the same with income tax cuts -- someone things their $500 tax cut is great, but ignores the $5000 tax cut those on higher incomes (whether wages or company/real estate ownership) receives, and then complains when there are more homeless people and schools can hire enough teachers. It's bait and switch on a generational scale.
