I’m pretty sure the other guy was referring to income tax. Sales tax is obviously going to be payed. These small taxes paid are still negligible in .

Did you even read my comment? A person making minimum wage that has dependents pays little to nothing in income tax and likely gets a tax credit. Sales tax would be 6.25 to 8.25% in Texas. Income tax for a family making $70,000 per year comes out to about 7% at most.

After researching I found that America does have social safety net, so taxes do go directly to illegal immigrants.

That depends on the state. States can choose who to provide those services to. Often need a social security number to access a lot of those programs.
