So. When you retire, and stop working at your current job, you get cows and you now have a new job… I do hope cows are liquid assets in Zimbabwe in the future.
Cows are always liquid assets in Zimbabwe and Africa. They are the currency for dowry (bride price). There is never a day when you cannot liquidate a cow.
I guess assumptions we have don't hold in Zimbabwe. Retirement age is probably earlier and Retirees are healthier. People have way more children and grand-children (so more family for mutual support and taking advantage of the cattle). Retirement is shorter. Just guessing here.
