For the reference of FreeOnes readers, so they may compare their financial situation with Eva's:
An E-4 (Specialist) with less than two years' service in the Army earns a base monthly salary of $1889.70 per month. He also gets a Basic Allowance for Subsistence (BAS) of $267.18, a Family Separation Allowance of $250, Hazardous Duty Pay of $225, Hardship Duty Pay of $100, and a Basic Allowance for Housing (at the Los Angeles, California rate) of $1561 to pay his family's rent.
When serving in Iraq, all this money is tax-free. That's a net income of $51,514.56 per year after taxes. Compare to your pre-tax income of about $65,000. (Now, you're not being shot at, of course, but still...) Eva's man brings in $65,000 a year, and she can bring down $5000 a week getting fucked for video. But you should pay her phone bill.
