My daughter, who's a class mother, tells me that when they're collecting for a teacher's gift around Christmas, the parents they have the hardest time getting money out of is the people living in the neighborhoods where the houses go for more than 750k. I know for a fact many of those folks are living paycheck to paycheck.
Listening to the moms at my kids school and listening to them brag about all the things they have .. doesn't take much to realize their $$$ signs don't match up what they are brining in each month
