@Laotionne - I looked it up, and the yearly median income for an extruder operator is in the mid 30s. Of course, the actual pay depends on where you work, who you work for and your exact position, but that is a general guideline. That's not bad for a position that doesn't require a post high school education.
I like that you can go right to work and then get the training you need as you work and earn money. Not everyone is cut out for going to school and attending classes Also, if you do a good job and move up in position then you can expect your salary to go up as well, so $35,000 a year is not necessarily the end of the line.
