There are 330,000,000 people in the USA. 1% of that is 3,300,000 people. Therefore, the Portland-Vancouver MSA (only 2.2 million people) does not exist for any nationwide consideration.
You announced that below some percentage of the population, people don't matter and shouldn't be accommodated. By your logic, I showed that Portland doesn't matter.

We accommodate disability because it is the right thing to do. We require businesses to spend extra money, lowering their profits, in order to put in ramps and openable doors, in the name of our common humanity. Not everything is done for a profit motive; not everything should be done for profit motives.
