It is funny, in Spain if you want to legally trade your own services, say you make websites, then you have to become "autonomo" - like self-employed, and pay between 60 to 100 euros a month taxes even if you make no money as self-employed. hahaha. That after you will have to pay a lawyer some 60 more euros a month to deal with the shitload of papers and nonsense.
You know these "taxes" in theory seem like a decent idea: take a bit of money from each citizen, to then put that money into healthcare and other things that will be free for these "citizens".
In practice it is shitshow of corruption and making the rich richer. And a huge pain in the ass for everyone. I would not mind contributing 20% of my "income" to a tribe if I get free healthcare and other benefits, but only if it was made simple and you could see the effect of your contribution.
Spain seems like the capital of papers and nonsense. But the entire world is like that one way of another...
Such a wasted time on the most "unique" planet in the universe. Deal with papers, try to survive, be busy with nothing things... No thank you!
So yeah, in a trade based society is not enough to "trade", you have to do it in a particular way. And if you are poor you are entirely fucked to begin with anyway.
