In my opinion, it is good for the wife to generate income and be independent monetarily speaking, but on the other hand the ideal is that you can raise your child and that means being at home, attentive and guiding! So, many miss that stage just because they work, I personally never saw my parents only at night and on occasional days because they were literally always working. So I consider that there is a better way where at least one parent accompanies the child most of the time, to take care of him and guide him, while the other who works complements with the upbringing and the home during his stay at home free from work.
