Rich people and lawyers make all the laws and regulations. Now, in all honesty, who do you think is going to benefit more from those laws and regulations?
There are ideas out there from improving gas mileage (over 200MPG, yes 200) to cutting costs of heating/cooling (1/5 the cost) a home which will never see the light of day due to the guys not having money to file the patents.
Inventors are just that. They invent. They suck at writting business plans and making presentations to potential investors. So, unless you are already rich, you can just about give up on any idea which involves a patent.
I have known many brilliant people who will die poor and frustrated. They have brilliant ideas. Spend most of thie life trying to get enough money together to build a working model, and that is where it ends. The model works, but no one cares.
