Democrat congressional staff shocked that they couldn't foresee increases in their health insurance premiums

Democrat congressional staff are "shocked" by how much Obamacare is increasing their insurance premiums?  Aren't these the very people who oversaw the writing and evaluation of Obamacare?  But if these staff can't even come close to foreseeing the implications for their own insurance, how much do they really understand health insurance?

Politicians seem to think if they just pass a law they can just mandate what they want and ignore the laws of economics.

From Politico:

Veteran House Democratic aides are sick over the insurance prices they’ll pay under Obamacare, and they’re scrambling to find a cure. 

“In a shock to the system, the older staff in my office (folks over 59) have now found out their personal health insurance costs (even with the government contribution) have gone up 3-4 times what they were paying before,” Minh Ta, chief of staff to Rep. Gwen Moore (D-Wis.), wrote to fellow Democratic chiefs of staff in an email message obtained by POLITICO. “Simply unacceptable.” 

In the email, Ta noted that older congressional staffs may leave their jobs because of the change to their health insurance. . . .
