On the one hand, the most realistic way to not have to work in our current society is to have enough assets that you can support yourself (and maybe a family) on the resulting interest generated from those assets.
On the other hand, the existence of the concept of interest is probably the single largest driver of inequality in the world. No matter how minute a percentage, if interest exists and you have enough money, your money will be able to make more money per hour than even the most skilled laborer.
Do you think interest has a place in the world, or should it be done away with entirely? Why or why not?
