I think that it is better to create a separate thread to continue on the above title instead of OTing in the original thread.
A continuation from here :
As for how the lecturer obtained the cash of $500k or $1.6m to buy the shares, I wouldn't want to speculate. A NTU lecturer earns more than $12k per month; annual income of more than $100k easily. He could have savings, properties on hands, etc which can be pledged as collaterals to obtain the financing to buy those shares.
Putting the lecturer aside who is considered as an high income earner, There are many cash rich people around. It is just like we don't know.
You won't know who are cash rich around you such as your closest friends, colleagues, relatives or sometimes even family members because most people do not want people to know their wealth.
