These 30.6 million people in wheelchairs or with walkers matter. They have worth and feelings and value. They also make up less than 1% of the United States.
Returning to this, I love how he throws out 30.6 million to show how huge the number of disabled people is to show how important it is, then says the "less than 1%" to make that number once again be really small.
The end message is "In every 1% of the population, there is actually 10% of the population. So don't neglect that 1%, because they're actually 10%."
