Why even innocent people are not helped by Krishna in material growth?

Because, they are innocent.  

Krishna gives the topmost benefit of the eternal life in His kingdom.

But, He does not give material success for the innocent people!

He does not like to give material success to the material people.

Because material success needs clever mind and timely implementation.

How can a person who is innocent can come up in life?  

Who said you to be innocent if you like to achieve materially?  

Did Krishna tell Arjuna to be innocent?  

I too have helped some people innocently as requested by them, but, finally, they could not tolerate my growth and hence started to act against me.  

So, this shows that innocent persons can not come up in life.  

So, my request to all the devotees is: 

Don’t be innocent.  Be innocent only to selected and trusted people and only in your approach towards Krishna. 

Unless you are under your regular self evaluation, you will be exploited.  

The devotees should be intelligent and think 100 times before accepting any person or any offer or any help.  

You should not be casual in material efforts thinking that Krishna will protect you.

The fact is, you are not using the intelligence that is the representation of Krishna, as said by Him in Gita.

So, do not be innocent,but be intellgent if you want material success.

BE INNOCENT ONLY TOWARDS KRISHNA!  IT WILL GIVE YOU KRISHNA HIMSELF.

Then, there is no failure in both material and spiritual life..
