I think the point to be made is if you want to be rich dont be a lawyer. Be a business owner or a top tier banker/investment or PE manager.

Being a lawyer is to trade the highest earning potential for stability and slow and steady growth in income over the years in tandem with your professional experience.

It is a profession which provides a gateway to a middle to slightly-upper-middle class income at relatively low barriers to entry. All you need is to get into NUS / SMU (or buy your way into a 2nd or 3rd tier overseas law school if your grades can't make it). Compared to finance where only the 5% of outstanding new business graduates make it to prestigious roles in banking and the top 5% of them have prestigious exit options into PE or IM.
