Singapore these days is overrun by mainland Chinese and foreigners. Not to be racist but they've spoilt the image I've had of Singapore since I was young. Singapore used to be clean, everyone spoke English, little to no crimes, even the low cost places were quite comfortable and relatively decent.
These days if it's not a mainland Chinese person spitting on the road, making insanely loud obscene noises or talking really loud in the MRTs then it's an another foreigner with their bags and bags of weird funky smelling stuff and/or body odor in MRTs. Even the locals are complaining about these foreigners taking over their jobs (low cost workers), taking over their men / women (a lot of "free love" apparently) and basically doing what the Nigerians do to a neighborhood when they move in. Not saying all Africans are bad, just that when there's a bad one, they really destroy a neighborhood.
Even Crime in Sgp has been on a rise. Still less than M'sia but more than what I'm used to seeing in Sgp!
