You sound like a hater. How else are people supposed to get started? It's a progression, you start as an amateur, and if you're fortunate enough, you become a professional. If you produce music, then you're a producer, it's simple as that. Now, if you don't have any song placements, you're not a credited producer, but nevertheless you're a producer.
And it ain't no such thing as fundementals of production. You make what you think sounds nice, and it's a beat. It ain't no rules to making music. Thats the opposite of what hip hop is. You do what's comes to you naturally and express yourself organically without preconceived barriers.
And it's not always about making money. I make beats. I've sold beats. I've also given away beats. I do this shyt for fun as and as a way to express myself artiscally. I don't want to be a producer. It's not worth the effort and it's not lucrative enough for me. But it's nothing wrong with people who aspire to acommplish being a professional producer.
With the mind frame you have, how would anyone ascend from an amateur level to a professional level at anything in life? Your same rhetoric can be applied to writers, painters, actors, etc... Basically anything that has to do with the arts. That way of thinking is shortsighted and narrow minded.
