Lisa Furia stated her message RE: Social security as an 
intergenerational concern:

  "Five of my friends recently did the math and found that the 
  additional amount of money they bring home with both parents 
  working after paying for day care is negligible - in fact, 
  detrimental as in some cases it puts them into a higher tax 
  liablility situation. Many have opted for one income, and 
  cutting back on expenses."

Lisa Furia went on to say in her post RE: success of socialism?!?:
"I think there is something terribly wrong when a valid decision 
for young mothers can often NOT be 'stay at home with the kids' 
because 2 incomes are needed simply to get by let alone save for 
ducations, take care of elderly parents, buy health care and 
other 'necessities'."

I am trying to reconcile the two but have been unable to do so.

In the first quote you indicate that two-income families do not 
benefit from the second income after day care costs are factored
in.  The second quote indicates that mothers do not have the 
option to stay at home with the children because the second 
income is needed.  However, that second income does not bring a 
benefit in that it is consumed by day care costs.

The two points of view are at odds with each other.
