Even if you are NOT in debt, you are still their slave, UNLESS, you call the necessity for employment (so you can buy food and other needed items) NOT debt.

Just because a person or family has no debt, if they are not producing their "own" or exchanging, etc., they REQUIRE money, thus a means to obtain it. Most have jobs for that reason.

In a peculiar way, if you have to go to the grocery store/other stores to purchase, you are in debt to the required purchases.

What's the difference whether you owe money to a bank or "owe" it (required to pay) to a grocery store (from your job-income) so you can eat? The difference is slight.

GROW YOUR OWN; PRODUCE YOUR OWN, then you will even be more out of debt.

TO BE as far out of the system as possible requires more independence than just being out of debt (thought that surely is a good start).
