I believe that many of these tiny businesses misjudge the expense of everything that goes into forming a group, but there is a distinction to be made between being able to spend money and being able to afford it. You'll need a lot of additional cash to sustain this organisation, and you're not even paying them, putting them in serious debt. All of the proceeds go to the song, music video, publicity, and personnel, and they don't make much money to begin with.
It's becoming increasingly clear that these businesses underestimate or miscalculate the amount of money required to finance a female group. Let's be honest: Kpop, especially for girl groups, is a double-edged blade. They're EXTREMELY hit-or-miss, whereas boy bands are a safer bet, and that's the unfortunate fact. So, clearly, funding a lady group would be more expensive than funding a masculine group. To get even the tiniest bit of attention, they'll need a lot of stage costumes, regular advertising, and a high-quality MV with a catchy high-quality song. They are also under the pressure of sticking out. Boy bands with these qualities tend to gain a basic following fast, even if it isn't a large one. There's still some cash in the bank. It's just not the same when it comes to girl groups. Even after five comebacks, they sometimes just don't attract any attention.
So, unless these tiny businesses have a lot of money and at least another three or four comebacks to test the waters, they should really evaluate if training and launching a female group is a smart idea in the first place.
I just want to clarify that I'm not suggesting or insinuating that businesses should debut more guy groups; I'm simply stating that it all comes down to finance, and girl groups demand far more funding than these organisations can afford. So, why would you do that just to have the girl group split after their first song or comeback due to a lack of funding? Before you started casting ladies to train, you should have assessed and evaluated what you were getting yourself into.
