Why don't the rich work 40 hours of earned income jobs? I know why-because they are going from investment to investment and business to business. They are accumulating assets that will make them money while they sleep.
Yes, those of us born without assets will have to join the workforce. But our work can't stop with our earned income job. We need to obtain (buy, build, or create) assets at all costs.
Building income streams will require our free time. We need to read and take action to start businesses, build dividend portfolios, and create rental income. The harder we work for ourselves, the faster we buy our freedom from the workforce.
