Way back when - society was based on trade.
Not necessarily of money, but of goods, food, services, help in times of harvest etc. Villages all came together for the springcleaning, for the preparation of feasts, and all shared what they had and traded fairly with eachother based on the needs of others.
For some, bread was scarce but could be traded for in return for tending animals or helping others with harvest. For others, food was plentiful, but the chores too many, so for them the help was needed lest all they had would decay.
Now, the society has changed. Villages no longer function the same way and trading has changed.
Money is the monetary unit that allows equal trades even between those who do not have skills or produce to trade with eachother.
If you were a blacksmith in need of food, you would have to find someone willing to feed you (and possibly your family aswell) for the work you could do for them in return.
Nowadays, a blacksmith can sell his/her wares to those who are interested, take the money and buy whatever food they want.
Money is often seen as the "evil" in society because there is so much focus on it. But few remember that it is the most neutral thing to trade..
Money given to someone for a service or product can then be converted to whatever the person it has been given to needs.
And I also agree to some part with both sides.
Tarot for me is a spiritual thing, but also a psychological thing.
For friends and for those who need my help (sometimes I have been approached and asked for advice) I'm happy to do an occational reading. But if I were to do it more often, on a regular basis, maybe even instead of my dayjob - I wouldn't survive if I did not get paid.
But I wouldn't get paid for the spiritual side of it since I keep that separate.
What I would be getting paid for is the time, the knowledge I can share, the insights I can give and the advice the querent came in search of.
We may all be spiritual beeings, but we all reside in physical bodies that must be fed, clothed and have a warm dry place to rest at night.
