Weâve been drowning in a flood of low-wage jobs for the last 40 years. Most of the income of people in poverty comes from work. According to the most recent data available from the Census Bureau, 104 million people â a third of the population â have annual incomes below twice the poverty line, less than $38,000 for a family of three. They struggle to make ends meet every month.

Fetal ultrasound. Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing. Ultrasound is no different from 'normal' (audible) sound in its physical properties, except in that humans cannot hear it. This limit varies from person to person and is approximately 20 kilohertz (20,000 hertz) in healthy, young adults. Ultrasound devices operate with frequencies from 20 kHz up to several gigahertz.
