We remember him as a PAP MP.
What has he done as a MP ? It's not free, okay ? The citizens of Singapore paid him a very handsome MP allowance.
Reference from Wiki:
CPF for Tertiary Education
In 1988, Tan Cheng Bock, as GPC Chairman for Education, led a team of MPs to argue for the use of CPF for education, as an appreciable number of able students were not able to enter local universities due to limited places. Tan felt that education was a form of investment, and that all his GPC was asking for was an extra option for CPF members, to let them decide whether to put their investible savings in stocks and shares or in education. Chief argument against the idea was that the use of such retirement savings may leave the account holder with an insufficient amount at the end of his working life. The Minister for Labour at that time, Lee Yock Suan said that there were alternatives available such as soft loan schemes which were interest free. In answer to Tan's claim that Lee had not clearly stated his position on the issue despite the idea being first mentioned years ago, Lee insisted that his position had always been plain, that he "was against it, but you have pressed me to study it and I shall"[6]. The set of guidelines on the use of CPF for Education proposed by the GPC was eventually implemented, paving the way for the beginnings of a wave of Singaporean students studying at overseas universities
Free parking
Tan also convinced the Ministry of National Development (MND) to let Singaporeans park their cars for free in HDB estates on Sundays and public holidays, to promote family togetherness.
Nominated Member of Parliament Scheme
Tan Cheng Bock actually voted against his own party despite the Whip not lifted (a first in the history of Singapore politics) regarding the NMP scheme, on grounds that MPs had to be elected by the people and be accountable to an electorate for their views. He received a warning for his action.
Think Singaporeans
FirstIn 1999, when the nation was recovering from the Asian Financial Crisis, and experiencing yet labour talent shortages in several key sectors, the PAP pushed for a stronger intake of foreign talent to fill the ranks. Although not against this rationale, Tan Cheng Bock argued that the Government should tone down its calls for the recruitment of foreign talent and reassure Singaporeans that they came first, [9] which earned him strong rebuttals, including one from then Minister of Trade and Industry BG Yeo and a stern rebuke from then Senior Minister Lee Kuan Yew.
For this, I'm supporting TCB, even though he is a former PAP man.
