Forced savings like done in Quebec, Canada is likely the best model for most people even though I dont like it as an individual that knows how to manage its portfolio. It also has the benefit of creating a sovereign wealth fund that can invest locally and be an economic driver but independent from the government.
I actually like the forced saving of Québec. I also have a defined benefit pension plan, a TFSA and RRSP but I am happy to be forced to contribute the RRQ for the general welfare of the province even though I know how manage my portfolio.
Considering that they also have to consider economic development in their investment decisions, the RRQ funds are well managed by the CDPQ.
