Researchers are tackling the problem of extending the human lifespan.

I am very much in favor of this, but we will have even more need to reduce the birth rate.

Supposing we reduce the birth rate sufficiently, I expect life extension won't cause economic problems. This is because by the time these treatments work well and are quite common, developed countries will probably have an economic system that doesn't require people to work, and most people won't be able to find any work.

But we can't take that for granted. If the plutocrats win, they could force most people into Hunger Games poverty that few will want to extend.
