Everyone I know who has "fuck you" money either works a lot more than 9-5 or a lot less. The men working 60+ hours a week are making money on volume of time and have a passion for what they do. The men working 40 hours a week are not working 9-5, they're working more like 6 AM - 6 PM 3 days a week and then working from home for the last 4 hours, though these men occasionally have longer work weeks and usually transition into the 60+ hours a week category after promotion. The men working less than 40 hours a week are not making the majority of their money by the hour.
