here is whats wrong.
in China you can make that tube for 5 dollars or less.
that is because China is over developing as part of their attempt to become
and remain an economic force rivaling western economies.
they have a glut of raw materials and cheap manpower.
they will make and sell anything anywhere at any price point and quality standard you want.
from a strictly consumer stand point that is good.
from a national economic stand point not so good for us.
barring any future trade agreements with the Chinese the
next global war will be about what we are discussing here
along with other things.
