I believe on hindsight, he may wish that he withdrew that comment.
I read somewhere that he was a a SPF Scholar, and a DAC with the SPF, before becoming a candidate at Hougang SMC, where was not elected as an MP.
He is probably earning much more as a Mayor and MP, instead of DAC or by now DC with the SPF.
It pays to be a Scholar and well connected.
Would any of us "sell our soul"?
We may not be as committed and perservere like CSJ, but I believe that many of us or a huge majority of us, wll not sell our souls.
