Alright, here's how it works:
Say you own a moderately successful company that makes cardboard boxes. In order to make cardboard boxes, you constantly have to buy materials to make more boxes. In order to buy those materials, you need
cashflow.
Business is going well, problem is, you need more facilities to meet demand. You buy another building. You don't buy the new building with cash, you get a loan instead. You do this because you need
cashflow to pay for an increased amount of materials to meet increased demand. As long as your monthly sales outweigh your monthly overhead (which includes debt) you make
profit, i.e #winning#MAGA.
This just keeps going. You buy more factories, you buy more materials to make boxes, you make more money than it costs you to pay off your loans and suppliers, i.e.
profit.

Surplus refers to budgets, and profits are part of the budget. If there's a surplus, it means you made more
profit than you forecasted.
