Not getting into ANY politics (and this really isn't a politics issue anyway):
There are some good reasons why many places are expensive to do business (especially manufacturing) in. We do have higher costs than many parts of the country, some of these costs are due to a generally good education system that is responsible for the education of everybody designing and building products. We have strong environmental controls (not a bad thing overall), strong workplace safety rules (Cal-OSHA), a higher than average state minimum wage (which affects suppliers and every other cost too), higher than average land and property tax costs, more comprehensive health insurance requirements for those companies who do choose to offer health care, and let's not forget the ever increasing costs of product safety and emc regulatory compliance. Then, there's the cost of purchasing, fabricating and shipping mostly American materials by California labor and trucking (which have their own set of environmental and regulatory hurdles, and the costs of maintaining a comprehensive quality control and service department (including legacy parts) that still services amps that we built over 40 years ago.
Some companies are not as "full service" at this, it is one of the trade-offs between cost and customer service/support. For those who believe in high quality domestically produced products and long term support, yes it does cost more to produce them which is why they cost more. There is this business model which works for us and our customers, but there are also other business models (including the disposable product model) that appear to work well for other companies. You as a customer need to choose which model fits you the best, remembering not to be hypocritical, and that other customer's choices may be better for their needs and not suit yours.
I hope this helps the understanding.
