As we all know, mining is now completely centralized. Big money buys expensive equipment in the form of ASIC / GPU / FPGA devices and deprives everyone else of the right to participate in the issue of cryptocurrencies.
Normal people see it as an expensive item while business-minded people can see ways on getting that hardware on different ways without braking the bank. From buying second hand rigs to repairing them they can do anything on what they currently have just to participate on having a piece of that pie. Yes big mining farms are getting all the big pieces but they aren't the only ones benefiting from each block and lot of early adopters have gotten the biggest slices in the Bitcoin industry. If you still think that you can't afford to mine Bitcoin then I think it would be better for you just to buy them in an exchange and ride the trend for you to profit.
