well, i do not know about him. the most logical way is to start his own biz or investment. that is more secure than having a job.
When you have job, it is like a time bomb and it is closer to being explode when a person gets older.
Jobs are for young people to learn the ropes about life and then move on to having biz and investments.
You are right, jobs is for young adults to learn how to deal with customers, clients, colleagues, money and people management. Most jobs will not secure financial freedom except those in the senior management. One should transfer their skills and experience learned from their job to start their own business or trade in stocks/ Forex later on in life when they need more flexible job to take care of their children or elderly parents and employers who regard age as liability.
For the case of Ronald Ang, if he earned $15000 a month, he should have at least half a million in savings which is more than enough to set up a company or buy a franchise license. Or to retire and do full time trading from his own laptop at home. I may not know him, but perhaps he may be a person who blow all his savings in the stocks clash or Forex last year and ended up wanting to look for a job with much lesser salary than his last drawn pay.
