Mortgage projection is one side of story. The other side is how long can keep job. Singapore worships youth.
My ex-company "retrenchment" last year. All 20 executives forced to resign forgoing retrenchment benefit because company change corporate rules into one where cannot tahan work conditions imposed.
All 20 had been with company for years, thrown out in the cold to start corporate life afresh. Now 1 year after, only 5 below 30 years old, have stable job. Rest 15 older than 35, since Jan 2011 "retrenchment", had been in and out of jobs. Many corporate job now multi-task till people ding-dong, cannot stay. One multinational company S**m*ns rejected my 35-year-old ex-colleague for temp exhibition job because they want their brand to be associated with youth. Over 27 years old still accepted but must look teenager. Pay used to be $5-6k long hours, now lucky to get half that with 10x multi-functional workload increase. One already sold her punggol, as no job too long, bills building up.
CADC whom many workers contribute $1 per month off salary throughout their working life, refused help saying see MP. MP's ah goon (never get to meet MP due MP no sight, no sound) say can introduce $4.50 per hour job. $4.50 per hour job can afford 2-room hdb mah? No need eat? No need pay bills? Transport in Spore free izzit? HDB super fast when it comes to imposing rules but when it comes to adjusting grants higher to help offset the increased cost of flat pricing, no sight no sound also.
