It's true that people can have better living in JB or Malaysia.
It's true that people can have a bigger plot of freehold land plus a big nice bungalow sitting on that piece of land.
I have a lot of relatives who are malaysians and stay in Malaysia, but until Malaysia cleans up its car-jacking and robbery acts, I for one will not propose to anyone moving to Malaysia mainly for this reason.
Robberies in Malaysia do not just happen to Singaporeans. These Malaysian robbers are inhumane. They rob the old and elderly, the pregnant, even young children below 10 years old. In broad daylight. 80 yr old elderly grandma they can also rob and push her to ground. Young children with only pocket money of 10ringgit, they also threaten to kill if don't hand money over. They do this even to their own people.
Even Thailand does not have as much robberies as Malaysia.
There are pros and cons in any country. So one should weigh what are they looking for when they uproot and move. Eventually everyone has to admit, a lot of migrants will rather move to countries with a low crime rate rather than a place which is cheap but with high crime rate.
