Clean and safe menstrual pads, clean water, infrastructure, education, controlled agriculture. These are pillars of progress. Space programs are impressive, but are of very little consequence when half the population is so poor, they crap on the streets in plain sight at daylight. Meanwhile women are ashamed to hang their sanitary pads in the sun to properly disinfect them due to 3rd world superstitions about cleanness and evil spirits. There are grown men in India who don't even know that women have periods. Others bury their dead in the Ganges while downstream the same water is used for cooking and drinking.
