Show us that; checkable source. I'm calling B.S. on that.

Illegal immigrants are a net fiscal drain, meaning they receive more in government services than
they pay in taxes. This result is not due to laziness or fraud. Illegal immigrants actually have
high rates of work, and they do pay some taxes, including income and payroll taxes. The
fundamental reason that illegal immigrants are a net drain is that they have a low average
education level, which results in low average earnings and tax payments. It also means a large
share qualify for welfare programs, often receiving benefits on behalf of their U.S.-born
children. Like their less-educated and low-income U.S.-born counterparts, the tax payments of
illegal immigrants do not come close to covering the cost they create.
Using the National Academies’ estimate of immigrants’ net fiscal impact by education
level, we estimate that the lifetime fiscal drain (taxes paid minus costs) for each illegal
immigrant is about $68,000, although this estimate comes with some caveats.

Illegal immigrants make extensive use of welfare. Based on government data, we
estimate that 59 percent of households headed by illegal immigrants use one or more
major welfare programs, compared to 39 percent of households headed by the U.S.-born.
• Based on their use rate of major welfare programs, we estimate that illegal immigrants
receive $42 billion in benefits, or about 4 percent of the total cost of the cash, Medicaid,
food and housing programs examined in our study.
Use of emergency medical services is another area in which illegal immigrants create
significant fiscal costs. Prior research indicates that there are 5.8 million uninsured illegal
immigrants in the country in 2019, accounting for a little over one-fifth of the total
population without health insurance. The costs of providing care to them likely totals
some $7 billion annually.
Illegal immigrants do add perhaps $321 billion to the nation’s GDP, but this is not a
measure of their tax contributions or the benefits they create for the U.S.-born. Almost all
the increase in economic activity goes to the illegal immigrants themselves in the form of
wages
