From the House member's page:

The legislation responds to pressing labor shortages in essential industries by creating a market-driven temporary worker program that adapts to economic conditions. The bill creates a new H-2C nonimmigrant visa, available to employers who prove their positions have gone unfilled for three consecutive months and in areas where the unemployment rate is 7.9% or less. 

Wasn't this a pain point with H-1Bs? They want things to cost less but don't want to bring in cheap foreign labour to depress wages? How do they not understand supply and demand? "Go be a plumber, they make good money" "Wow, this quote I got from that plumber is so high" "Me be a plumber? No way"
