> my superannuation fund (401k, ROTH, IRA, hard to know what people call this in other economies)

In Canada, the comparable funds are: Canada Pension Plan (CPP, mandatory contribution for all employees), employer-managed pensions (not all companies have one; policies vary such as defined benefit vs. defined contribution), personal RRSP (you make the contribution and you select the investments).

I guess the comparable funds in the USA are: Social Security (mandatory contribution for all employees), employer-managed pensions (not all companies have one; policies vary such as DB vs. DC), personal IRA such as traditional/Roth.
