Just take Apple as one example.
Apple is sitting on close to $300+ billion in cash in some offshore tax haven, just to make sure that cash is located outside of the USA to insure it does not attract any tax.
This wide spread multi-national tax avoidance has been running at epidemic levels for many decades now.
From what I recall Google started this scam and it is still the master of avoiding tax and while the populous is happy to vote in governments that turn a blind eye to this practice, it will remain a very lucrative endeavour.
