Teaching people to control their costs, ala "mr money mustache" makes sense.
I personally believe that you can control your costs and raise a family on $30k/yr if you are educated on the bad choices not to make...several cars on loans, larger houses than needed, etc...
I genuinely don't know how a couple could raise one child on $30k/yr - is rent cheap where you live ?
If you had have asked me what a couple needs to raise a kid in the US, I would have guessed 80k.. maybe 60k if they are very careful with money management, as you suggest.
I'm actually being sincere.. but where I live rent is very high, so perhaps that explains the vast difference ?
