I guess my thought process goes similar to this.
I am one person out of 7 billion. I need to provide for myself, everything I pay must cover the costs of all the costs of those people I bought from. When people buy my labour they must cover my costs of providing for everyone else.
My work and the work those people are doing needs to pay all those costs. We effectively pay eachother to work at what we are independently good at - trade.
But a worker only receives revenue from the work they do (I'm excluding unearned income)
If everyone gets everything they need ultimately from other people, and each of those people needs to get everything they need from everyone else - and sometimes the same people.
Where does the salary of the workers I buy things from come from?
I feel intuitively it doesn't matter how much bread someone can create, the total revenues from selling bread in general needs to cover the costs of all their employees and the business costs themselves.
But this process repeats for all transactions the total transactions for MasterCard pays the bills that MasterCard employees have.
Everyone needs to earn more than they cost but so does everyone else! How can this not inflate endlessly over time?
When I look at government deficit and debt levels of the world, people don't produce more than they cost and relative and absolute poverty.
