from a simplified economical situation taking up debt is recommended, as long as the value-growth of all your assets exceeds the interest you pay for the loans. And Barca does that. That's how an economist and market optimist would tell you at least.
Realistically Barca is in a bubble. In the original sense debt is just meant to be a temporary financial boost to startup or boost your business that you are going to repay eventually. But Barca, like so many capitalist societies, see debt as permanent. They exploit this system by just refinancing debt ad infinitim. Take a loan, use it to boost production/brand value and revenue, get approval for a bigger loan, and then use the bigger loan to pay off the old loan -> Rinse and repeat, and this will never stop until the market crashes, the bubble bursts and then we don't know what will happen but a lot of people will be in a lot of trouble.
