If you really want this, you can probably have it, and you needn't go anywhere near as far as murder to get it. I know of quite a few people who make a living through various types of contracting (software and mechanical engineering in the cases of two personal friends who do this) and take off a few months each year to travel and relax. It won't maximize your cash flow, but it could maximize your happiness if that's what would truly do it for you. I suggest that you seriously look into it and consider if that would give you more fulfillment :)

I desparately wish we as a society would stop clinging to the 40-hour work week and working non-stop until retirement. I don't think we live in a post-scarcity world, but we could sure make things easier on ourselves.
