well, the conventional financial economics is that, in the long run, the market (stock market) will go up. so short term fluctuations, are bound to be there.
yes, there's a risk to investment, and there's a downside. and since you are giving your money to be managed by professionals, you are relying on the expertise of the professionals rather than your own.
The reason why government is promoting is because to encourage investing from earlier on to build enough savings at retirement since based on findings by EPF, we don't have enough retirement savings.
in another point of view, by putting in FD, you lose to inflation. so end result is, you lose.
by investing, you may beat inflation and accumulate more wealth, and you may win. at least end result is not a certain lost. does that make sense?
PS: so, ya, by the time i retire i believe PRS should outpace FD by alot.

I see at least it is not a certain loss.makes total sense. Lacked knowledge in prs and doubted if it can even give a good return by retirement. read and heard that UT is "tipu" duit.
