I would tell your gf to find a new appt and move out. As a tenant she has rights too.
And if they try to take her to court to seek liquidated damages, it will get thrown out in a heartbeat.
Just tell them to get disability insurance, max out their 401k, and invest in a good S&P500 index for their other discretionary investments.
Something like 93% of advisors cant beat the S&P500 anyway.
GS is a complex business entity who the government and public have a mistrust for. Their business is so complex, that rather than try to understand it, the government feels the need to dismantle it.
