How low is too low?

According to the US Bureau of Labor Statistics, we are producing less and less apparel and textiles in America every year, and employment in apparel manufacturing is down about 80 percent in the last 20 years.  At the same time, we have been consistently spending at least $1500 per year per household for the last 20 years on apparel.  Much of our purchases are on imported items because they can be produced at a lower cost.  But how low is too low?
