The key is TEXAS.
Texas don't mess around.
The immigrants that come in have to work unless they live in
Houston, Dallas or Austin ... the liberal
holes in Texas.
I will not speak for Texans but the illegal aliens' behavior coming in there is much different than in CA, IL, NY, etc.
From the same Wiki Article:
Economic impact of illegal immigrants in the United States
The
Congressional Budget Office reported in 2007 that "the tax revenues that unauthorized immigrants generate for state and local governments do not offset the total cost of services provided to them" but "in aggregate and over the long term, tax revenues of all types generated by immigrants—both legal and unauthorized—exceed the cost of the services they use." Unauthorized immigrants demand goods and services while an estimated 50 to 75 percent pay taxes.
Due to cheaper labor, they contribute to lower prices in the industries where they work, such as agriculture, restaurants, and construction.
The study did nothing to capture and allocate the cost of US citizens displaced in the workplace.
Also from the same article:
In 2013, Robert Rector and Jason Richwine of
The Heritage Foundation released a study concluding that as of 2010, the "average unlawful immigrant household" had a net deficit (benefits received minus taxes paid) of $14,387 per household.
My take ... I tend to believe your numbers but that is just one aspect of the uncontrolled illegal alien overall problem.
