What will happen to the public transportation system if the foreigners disappeared today?

WARNING, TWISTED MATHS AHEAD.

While discussing on the topic of the impact of foreigners on public transport with my sister, I did some crazy maths and arrived at an another of my dark side theory.

The complaint revolves around that the fact that 40% of the people in Singapore are foreigners, which contribute to the over crowding in public transport in Singapore.

What will happen if they suddenly disappear? The $$$ minded train operators had to do something to retain profits at the current levels. Once you are used to good profits, you will want to keep going, no matter what. How?

1. Decrease the frequency of trains by 40% to keep the trains filled as much as possible. The trains will still be packed, and we are all going to be late.
   
   
2. Increase the train fares by 40% to boost revenues back to previous levels. A 40% hike with additional hikes due to inflation is going to be a killer.

There is also another way to solve the problem.

TURN THEM INTO CITIZENS ASAP.

Just 2 generations ago, we are all foreigners too. It wasn't long ago when this was a quiet fishing village until the British came along. Read your history people, Singapore has always been full of immigrants and foreign workers.
