This makes perfect sense. Do industrial machines compensate for this since they have a higher lift presser foot?

Other things to check for:
- a Singer sewing machine needle. If your sewing machine is not a Singer you should NOT use this brand of needle in it. If your sewing machine is a Singer than you MUST use this brand.
- that you have inserted the bobbin correctly, refer to your manual. Most (not all) bobbins are inserted so that the thread comes off the bobbin from the left to the right (when the thread tail is pulled, the bobbin will spin a a clockwise direction)

If your thread is unthreading from your needle as you start to sew, that means your take-up lever was in the down position. After you finish sewing a seam, turn your flywheel so that the take-up lever is in it's highest position, then cut the threads. If you get into the habit of doing this, your thread will never come out of the needle.
