Actually, that Trump prediction, if true, could help a lot.  

We got into this mess because the bureaucrats wanted to believe that 10% returns on the stock market were the new 'normal'.

They had forgotten the days of double digit inflation and double digit lending costs of the Carter years and proceeded with more optimism than was justified.

If Trump policies could get the stock market much better (something which is totally speculative) PERS could start to heal its self-inflicted wound.
