Slavery evolved and took on new names, but never disappeared.
How much do you have saved up, that you're willing to tap into so that you can live for yourself and others, and not a paycheck? How long could you just exist before the debt becomes crushing? That's the length of your leash.
Retired people who live comfortably are basically 'off leash' but still confined to the yard. Some people have a 1-2 week 'leash'. Some may have saved up enough to have a 6-12 month 'leash The rest are the 'i could stop working whenever I want, but refuse to' or 'man I'm so fucking far in debt that I'll never be able to stop fucking working'
Most people will never be able to stop working because I'm a slave based economy, a slave must earn it's food every day, and it's bed every night.
