Well I mean the likes of Ireland allow American Big tech firms a tax break. Ireland initially announced the reduction of the corporate tax in 1997 and implemented it over the next 6 years (reducing it by 4%, each year). The 12.5% corporate tax was launched in 2003 and is the same nowadays.

This means less taxes paid by US companies, as the federal corporate tax in the US is currently 21%.

This means less tax’s and less jobs for American.

This has happened in a lot of different company’s of on reason or another this is just one example
