Yeah, but those wealthy immigrants are wealthy and pay the lion's share of our taxes.  Something like 40-0dd percent of all taxes were paid by the top couple percent.  

We people making less than 100k/year are paying not as much of the tax.  Why would the government look to the poor people for taxes when they can let in foreigners with their billions of dollars, they buy inflated properties and pay tax on them, bring high end luxury brands and businesses to the area and generally turn it into a gentrified #nopoors place.
