Undocumented workers pay more in taxes than many giant corporations.

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.
