### Comment:
Now adjust for the percentage we have to spend on housing, tuition, child rearing, medical care.  
  
 What's left after those expenses now, compared to 20 years ago? 50 years ago? 
  
 Assuming two children I guess.

### REPLY:
That's literally what inflation is. 
  
 Housing is cheaper right now than 20 years ago.  A lot cheaper.  Tuition and medical are obviously out of control.  Child rearing is somewhat controversial, because while daycare services and healthcare for a child are outrageously more expensive, the 'stuff' for children is dramatically cheaper.  Diapers, formula, food, clothing, toys, books, shoes, car seats, etc.  All significantly cheaper now.
