Hi Trust -
I don't know you personally, but I can appreciate your frustration.
The wholesale price of land and tier is determined by Linden Labs. Current costs for a full Estate Sim of 65,536m with 15,000 prims, is $1675 USD when purchasing from Linden Labs. Tier cost is $295 USD per month billed to the Estate Owner. Mainland pricing and fees are different. Tier tends to be lower, but land cost is higher.
Fortunately, the Second Life in world economy is a "free market" economy, or about as close to one as you will find these days. Whatever profit (or losses!) Estate Owners or land dealers make is at the mercy of the market.
If you aren't happy with the current rates for land in Second Life, I suggest that you purchase your own land and pay tier directly to Linden Labs. Or, perhaps, create a more affordable alternative to Second Life!
Take care.
