Lol, applicable to me right now; this gad damn tax system for small businesses it's so painful and laborious; it costs you admin time, resources, and mental capacity. It's really a burden that, if lifted, I feel would unlock so much productivity.
If all you need to worry about is profit and loss, and working with the full margins, you can run more efficiently, hire more people, experiment on R&D to improve your product or service, and negotiate better rates from suppliers because you have more capital on hand.
Oh and eliminates wasted spend where business owners try to buy things they can as a tax right off, when they don't really need it
