How to tell that someone sucks?

I see it so many times that people are complaining that they don't get a shot in 5the industry. Complaining that we just go for young talents, that its only men or that a certain style is preferred.

They come up with whatever that is wrong when the real reason is that they suck. In reality, there is no chance that we can subsidize on quality or demand. If you suck as a songwriter it doesn't matter how many chances you get if you can't fulfill the task that is given to write a good song.

The problem is that no one has the guts to tell them where the real problem is. Instead, to get better they keep on doing the crap that won't lead to anything. It doesn't matter how many contacts you have to the industry if the work you do isn't up to the standard to a mass audience.

I don't want to be that person either that bring bad news. At the same time, if nowadays it wouldn't be so damn uptight with a generation that will break down on the smallest obstacle and the mind to think that they deserve the success by do nothing or learn by mistakes, it's not worth it to call out where the problem is.

Should you say if someone sucks?

Realize what you are good at. I figured out quite fast that I really suck playing an instrument. I was good planning and get the artist opportunities and get things done. So I became the record label or management etc.

So for me to go and learn how to play guitar for two years and then try to join the bands I work with is not a good idea.

If I tried it would anyone stop me? Would anyone stand up and just say - Peter you suck at playing guitar!

I mean I know I'm just not good at it. Even with lessons, I would not be near as good as the guitarists I work with. Even with 10 000 hours of practice, I will not get close. 

Now I know this by myself but lately, I have seen people doing kind of this error in other parts of the industry and I cringe but are unsure if I should stand up and just tell them - you are really not suited for doing this.

I guess no one would do that with my guitar play either. They would just let me be and hope that I don't invite myself to their tours or practice. But then if keep begging to play the solo on their next recording? Or even go out seeking other bands telling them I'm a really good guitarist? Would they stop me?

I guess no.

Would I like them to do it? I don't know.

So when I see this my dilemma is to know if I should stand up and say something or not?

The hard part is that I see them digging a deeper and deeper hole every day.
