I think about this from time to time for women that I know.
The lack of a verifiable work history will make it extremely difficult for the
woman to obtain employment when she goes to seek employment.
Not only does an employer want the applicant to be qualified (degreed,
certified, licensed, etc.), but they will want them to have experience in
that field.
Another down-side to the sex trade is that there is no IRA, 401K, Social
Security, pension plan, disability insurance, or other mechanism in place for
when a woman wants / needs to hang up her "fuck me pumps".
A happy medum or compromise is to work a legit job, and supplement her
income from the sex trade. That way she can also build a credit history.
And when one of them "snitchin bitches" that she calls friend dimes on her to
the IRS or State Department of Revenue, she can explain that Benz she
drives, and all the Gucci, Pucci, and Fiorruci she rocks.
