is this helpful economic activity? selling colour books and stickers? why don't you call them what they are, which is buskers.
i would have more respect for the busker than the entrepreneur, and would choose the term busker over the term entrepreneur if given the choice. the busker is an artist, they are real and they have an air of blood and sweat and toil. the entrepreneur does no work of their own but pays others to work for them via bank loans on collateral from their inheritance, and uses the surplus value to buy fancy shoes made by six year olds at gun point.
the busker asks for little, and deserves respect for it; the entrepreneur demands respect, and deserves only contempt in return.
but, from the state's perspective, this is juvenile. just build them the goddamned house. don't make them give you a fucking sticker for it. it's a waste of time and a waste of resources, all so they can show they are a part of the elect. as a society, we need to grow up and move on past the childishness of entrepreneurialism.
