Yes, human powered ferris wheels.....found only in places where you can pay people less than $1 a day for their labor.
See when businesses have access to very cheap labor they stop investing in machines, software and processes to improve productivity. That what economists looking at our productivity growth's correlation with foreign imported labor numbers will tell you. However, this simple conclusion also it means that PAP govt has made a serious mistake to open the floodgates to cheap foreign labor causing a decline in worker productivity. However, if you look at the speeches by the SM and PM, they put the responsibility of increasing productivity on the shoulders of Singapore workers and businesses. If workers and businesses can't improve their productivity, Singapore will have no choice but to continue importing foreign workers. The PAP govt has never admitted that its liberal foreign labor policy CAUSED a fall in productivity.... so it was left to MP Low to fire his salvo at the govt and put the blame for productivity decline directly on govt foreign labor policy :
The Singapore worker can train, retrain, upgrade all he wants but if companies have access to cheap labor like ferris wheel operators in India, they will never buy machines that will make full use of the skills of the Singaporean worker. That is why in Japan which uses almost exclusively more expensive local labor has a productivity index of 100 compared with 50 for Singapore. By saying that Singapore needs to improve productivity to decrease reliance on foreign workers, the govt has reversed the real cause and effect i.e. the govt is saying our reliance on foreign workers is caused by our declining productivity. The 1st step to fixing a problem is to admit that a mistake has been made. MP Low's speech in parliament only elicited denials from the PAP side...so I'm not optimistic the PAP will adopt the right approach to improve the lot of our workers.
