There are 2 major reasons why people choose to use layers of corporations in other countries: tax minimization (in their domestic country) and obscurity of the assets-owners relationship.
The latter is used by corrupt politicians, oligarchs (extremely wealthy people who have massive influence on policy/politics), and to stifle investigations by civil investigations (divorce), to stifle criminal investigations (political corruption, sanctions avoidance, fences for thieves, a convenient vehicle for transactions or large assets so governments/ oversight can’t easily track them).
There is a minimum overhead required (you need at least a part time CPA and attorney to give you the strategy, more if they actually implement it), but I don’t think it requires you be ultra wealthy. The problem is that most law-abiding, non-sociopath people don’t benefit much from avoiding the law.
