Is it ok to copy a W5 head and make it better or are we just mad at Speedmaster

Welp people in Merika want 35 dollars an hour plus the boss needs their cut plus US taxes plus shipping of the raw materials maintenance of equipment and the electric bill etc. etc. etc. a basic business course should be given in High school I believe...people I know used to always want me to do "side work " auto repair but they'd ***** no matter what the bill was it usually came out to "half of it was the parts..." most of the time I was lucky to make 15 an hour...that got old cheap parts wouldnt cut it if they are back bitching again inside of 3 or 4 months...
