Look back at the history, the rulers were always the one who enjoys, decides and plans for the commoners. I am also one of the commoners who cannot change anything. Just carry on working, fight for your family and earn money for your meals and shelters.
Honestly I am not proud to be a Singaporean but neither am I proud to be of any national citizen because everywhere is the same. I am chosen to be born here so I am a Singaporean and that's it. When there is politic, there will be bias and unequal treatment. Humans have the tendency to fight for what is best for them, the politicians, the commoners, everybody... Everyone is selfish. Since young, our textbook always tells us not to be a liar and not to be selfish. Come on! You have to be a liar and be selfish to work in the industry, but you have to be an A plus scholar in lying and being selfish to be a politician.
Whether you choose to migrate overseas or people choose to migrate here, it does not really concern you or me. Migrating is for the sake of convenience, if you have a job overseas or you have your family overseas, just migrate. Everywhere is still the same, we are still humans living on this earth.
If Singapore is a place where horrifying things happen to you, you can always choose to leave. On a side note, even if the place you live has changed, if your heart doesn't, nothing will change except for your location. You can be happy if you choose to be.
