After all btc is mined?

So i know that it's a long ways away, but when all the Bitcoins are mined and miners only earn transaction fees, what will happen to the miners and the industry? Will fees alone sustain miners with enough profit to even mine? Will there even be enough transactions since BTC has found it's meaning as a store of value and not really a daily transacted currency? Will these big mining companies capitulate, thus creating a shift and incentives for smaller individual miners to flourish and start mining?
