Undocumented workers pay more in taxes than many giant corporations.

Pretty much.

That and the estimates are that about 10 to 15 undocumented immigrants live in the US out of 350 million.

Complaining that they are the cause of any problem is screaming "I can't do basic math."

Big corporations have offices in most countries around the world. Not all countries have the same rate of corporate tax. Ireland has one of the lowest rates of corporate tax in the OECD. It taxes companies that earn over 750 million Euros in the last 4 years a rate of 15% so large tech companies have their tax paying offices set up in Ireland.
It’s all legitimate but not every country is happy about it.

Maybe they pay more in taxes because since they are undocumented, they can't file tax returns. Since they can't file tax returns, they can't get refunds or take tax deductions so any monies taken out of their pay goes to the gov't.

they will be deported to their miserable existance

Immigrants are criminalized like the homeless. Deal with it. You ain't no socialist country.
