Of course it is!

If it costs you $1 per day to live (all-in, all expenses), and you can only make $0.95 per day - then you are doomed!

Of course, it doesn't just have to be cash: if you're a farmer, and you eat more than you produce, you will starve!

However you look at it, if your outgoings (in whatever form) exceed your income - you are bankrupt.


But what's the use of that if it leaves you out-of-pocket?!
You won't be able to continue indefinitely - something will suffer, and this will lead to unsatisfied customers in the end!
