There are serious problems facing mankind. Drinking water shortages, pollution problems, lumber shortages, and poverty. David's observations should be heeded. In 2015, more than 50% of United States workers are getting paid $15 or less an hour, which means they are barely getting by. These people cannot afford to retire. We should have a national health care service that would serve the health care needs of all Americans. The income and the accumulated wealth of the richest 1% of Americans should be heavily taxed since they own as much wealth as the poorest 95% of Americans.
