Important to emphasize the up to, I think. 3.6M a year is a large amount to invest on most salaries. Given that most working people should look at iDeCo first, the likelihood of being able to max everything out is quite low.
As noted by someone else, for those young enough (around 30?), 100k a month plus their iDeCo is a great strategy.
As you said before, Adamu, we don't want to scare people away. 50k a month, 100k a month, whatever you can afford will all be fruitful in the end.
Slow and steady...
