When he breaks a leg and can’t work for a while, it’s inconvenient but not burdensome for your shared business. But, you chose not to get health insurance. Your melanoma diagnosis looks like $80,000 which you don’t have. Your business partner has a choice: should he liquidate the business, or act in the long term?
