The developed world has tame poverty to a reasonable extent via the instrumentality of technology.If you watch the difference between old stone age and new stone age,you will know is technology.All the sectors starting from agricultural,financial,industrial and educational tor you will see that technology has brought a lot of calculated transformation to the extent that technology triggered high productivity meaning what 100 men could do in one month, with technology,it will be done in a day.
You're right that technology creates much more wealth. Many types of technology can increase production by 100 times or more. You say that the developed world has tamed poverty thanks to technology.

Sure, there is some more tax money paid, but most of the money goes making the rich get richer.
