[In Time] how did the whole world get onto the "Time Economy"?

I understand it for the rich, those who potentially would never run out of money, but for everyone else it seems like a bad deal, even for the Middle-Upper Middle Class,  since you *might* live forever, but you can't retire

Just seems like a really bad choice to elect to die at a much younger age, rather than live for a guaranteed 70-80 years.

It's easy to see why rich people would like such a system - because it would let them be immortal. So maybe some wealthy employers just started refusing to pay their employees with cash, and started only hiring employees that were willing to use the time system. And then, as more and more employees were brought in to the time system, eventually time credits became the primary currency used in economies. Maybe?
