why does everyone ignore that hungary has had citizenship-based taxation, limited only by tax treaties and multiple nationalities but not by income or tax rate, since at least 2011?  hungary is the ultimate citizenship-based taxor. the us has a more than 100k income threshold and eritrea has a low tax rate it can't even enforce.  hungary can enforce and has a high tax rate of around 30++% if combined with mandatory social security.  the french law *should* also be limited by intntnl treaties, but remember that not all countries have treaties with each other.  in practice, this french law seems to target only wealthy people, while the hungarian one is targeting everyone, since there's no threshold.  btw, tajikistan also does citizenship-based taxation so that tweet is pretty wrong.
