I recently came to the same conclusion, but also realised that there is a lot more to it than just pay. Generalising here but switching for a similar role in the US will mean:
* No more free healthcare
* Much less PTO
* _Significantly_ less parental leave for you and your partner
* Less pension/401k contributions (typically)
* Generally longer hours and a more intense working culture
* Probably a higher cost of living
Depending on your new salary you may find that these downsides are offset by more cash in hand, which is great, but it is definitely not a one way street.
