The market is very unfair for normal human beings. Companies like BitFury pay as low as 3 cents in Kwh and also have tax-free zone, import miners without paying taxes and also pay zero tax in profits. If you have someone in the government, you'll be able to do that. Some people mine in places where electricity is free but you need someone from the government for that.

If you don't have access to free or very cheap electricity rates, then my suggestion to you is to not mine or only mine when Bitmain realises an asic miner for a coin that didn't have an asic before.

Easy to buy <-- Do you mean Bitcoin or mining equipment? I find buying of mining equipment very hard, I could never risk buying an Antminer from Bitmain from China cause I'm so afraid to receive a damaged miner. If any of them is damaged and I have to any of them back, the postal service in my country is so expensive that I'll pay the price of a mining equipment in shipment. That's why I have been sticking with GPU in the past, I'm sure Nvidia and AMD will give me a quality product.
