Anybody who can use a profit calculator can figure this out. You are thinking in terms of dollars and not crypto-currencies though, I personally have my own mining rig and am building them as fast as I can get GPUs, I understand that the difficulty will increase and 2 years from now the likelyhood of being able to mine the same currency with my current rigs is practically none, but what I can do at least is switch to whatever currency I can mine with GPUs. Now what I mean is don't think of your mining contract like it pays out dollars, because it doesn't it pays ETH, BTC, ETC. Right now my rig mines about 2.4 ETH a month, that comes out to 28.8 a year (Not accounting for difficulty increase but even if i end up with 15 at the end of the year because it doubles thats fine with me). The way you see it that would be about $8,064 in a year but the way I am looking at it is, BTC is hovering around 2k and has historically hit 3k, in the near future one bitcoin could be worth 10k each, I believe that ETH is going to overtake BTC in that case the price of ETH could reach upwards of $1,000 each in the next year or two, that means that when my investment in mining and holding ETH matures I will be able to cash out for about 15-28K a year on each computer with only a 3k investment. As opposed to buying 30 Ethereum now, I will be able to mine it, and continue to mine other currencies for years to come. I agree Genesis mining isn't as profitable as people make it out to be but its a good way for people to get their foot in the door and as an investment it has a better ROI than most things in this world if you aren't computer savvy.
