I listened to the videos and did not hear anything about them getting subsidies or being tax-free. Where I come from, $44K per year is not tax-free by any means, and it’s WAY over the limit for subsidies, free lunch, free medical care, etc. unless one of the parents is disabled. Maybe if you’re below $20K you can get that stuff, but back when I was a single mom making $30K I did not qualify for anything and I certainly paid taxes.
$44K for 7 people will net you all KINDS of subsidies in CA, at least. At the minimum, reduced electric costs(which are already inflated due to “tiers”), reduced gas and water, free breakfasts and lunches at school, energy efficiency programs which sometimes include energy efficient appliances, and possibly low cost medical insurance.
