The more things that you can do yourself is money you do not need to earn.
Earn money and they tax it.

I remember when doing things for yourself was common long ago.

Resoled your own shoes.
Made your own clothes.
I remember when feed sacks use to come in cotton cloth with print patterns on the cloth so you could re use the cloth for clothing.
Put down food supplies from the crops and livestock.
Had our own eggs, milk and the products from the milk we made ourself. Cottage cheese, butter, ice cream to name a few.

Burned wood for winter heat. Had a few dollars bought a ton of coal for a longer burn between feedin the fire.

Done our own mechanical work on vehicles. I still do that.

Fixed and repaired our own buildings.
Made our own furniture.

A lot of things can be done your self if the means are available.

We still made an  income for spending but was not necessary to make a lot.

I see a lot people out hustlin to make a dollar and by the time they are done buying they have less money left than I would making less money and doing more for my self.
