I don´t think it´s the age of the player that is creating a corp that really matters, but rather the reasons why people create corps is the problem.
Sure, there are inexperienced players who will make mistakes if they try to lead a corp. But making mistakes and learning things is not always a bad thing.
Now here is some speculation from my side (Yes, I have no data to back this up as I don´t believe such data really exists at this point. I can only go with my personal experience on the matter).
I would guess the number one reason for players of any age to create a new corp in high sec is tax evasion. Sometimes theses “tax evasion corps” will also recruit other players and will use the low tax rate as main selling point which sadly does work very often.
But in reality those corps have nothing to offer, in regards to teamplay or working towards a common goal they pretty much are just a shared chat channel. Those corps break apart as soon as they run into the slightest bit of trouble, these corps break apart in different forms.
Those corps however mark themselves as corps doing certain activities, they mostly end up being people playing solo and simply evading the npc corp tax. For the people who actually are interested in playing as a team and interacting with other people, there is no real way to filter out those corps. Which means a lot of potential recruits are “stolen” from corps who actually are interested in being a corp.
So what we have ended up with is a huge amount of corps that do not really have any purpose other than lower taxes, which at best only lead to frustration amongst players who actually are trying to find corps that are actual corporations, but keep ending up in corps without any goals and/or proper structure.
And here comes the part all carebears will hate me for:
This certainly is not a fix not get rid of bad corps, but it is a start of stomping corps that are created for one of the wrong reasons:
Change the tax structure:
1. Remove the NPC Corp Tax and replace it with a high sec tax. Income that was previously taxed by NPC corps should be subject to taxes for everyone who generates his income that way in high sec. Name it concord tax.
1.1. Everyone pays that equal tax for the safety mechanincs in high sec.
1.2. People who want to play solo are not forced into corps, they can stay on their own and on top of it don´t have to pay taxes if they venture into more dangerous space (in regards to game mechanics).
2. Taxes or parts of the taxes that have been payed could be refunded to the corp if the corp loses stuff in wars. (Only applies to losses in high sec!)
2.1. If corps make themselves open to the possibility of losing some of the protection they payed for I think it would be fair to get some ISK back to soften the blow if ships are lost.
2.2. Corps that actually work together can run pretty much all content in frigs / cruisers that can be easily replaced during war times.
2.3. Incursion corps certainly will have to use bigger toys to keep doing what they do, but with the amount of money they can make, they should end up paying that much in taxes that even non blingy battleship losses will be covered by reimbursement.
3. Corps which declare war are excluded from reimbursement, while any of those wars are still active.
In conclusion this could kill tax evasion corps. It still gives people the incentive to join corps. Wars become less hurtful for the victims as long as they play it smart.
DISCLAIMER: This is by no means a well thought out idea, basically it was just a brain fart that happened while reading the thread, however I stand by my opinion that the main problem with corporations is not the lack of experience of the members / leader, but rather the lack of a real purpose for the corps to exist in the first place.
