Too Good To Be True

You ever had an idea that you thought was really cool, that you just knew was totally impractical and unworkable?

What about an idea that you can't really see any problems with that is only held back by one tiny frustrating fact, usually something to do with profit margins or political will?

Here's a collection of great ideas whose lack of worldwide acceptance and execution I can't grasp. They're not all my ideas - a lot of them have been bounced around in my group of friends. If you see any problems that I don't pick up on, please, let me know - and why not toss in your own suggestions?

OMNISEX CUBICLED BATHROOMS
Nobody likes using a urinal. Let's face it, we're not cattle. Combine bathrooms, save space on the urinal section, stop discriminating passively against trans individuals and enforcing gender binary, and give us frigging cubicles.

SOLAR PANELS LITERALLY FUCKING EVERYWHERE
Glass exists that can generate electricity when the sun is shining on it. You can put solar panels on just about any external surface. They can be camouflaged to look less obvious. You can make solar roads. I look outside my house and I see no solar panels. There is a killing to be made here. Are we just waiting for literally the last crumb of coal to burn?

ACTUAL HOME ECONOMICS LESSONS
Home Economics - that's cooking, right? I agree that learning to cook is important, but at what point in school were you told how to pay your taxes, and what those taxes are? How expensive it is to actually live in a place of your own? What is insurance, exactly? Nobody should go to university without knowing this stuff.

WASTE FOOD LAWS
Give it to the homeless and the poor. This shouldn't require a law but it does, so we need one. France took the big step forward - the rest of the world needs to follow suit. Dad always taught me never to waste food, and supermarkets and restaurants should be no exception.

MINIMUM WAGE TIED TO LIVING WAGE
There are companies on earth that actually make this work. Seriously - when you are told by the country you live that your ability to not starve to death is less important than keeping Wal*Mart's profit margins low, then you're seeing the shitty side of the capitalist dream.

...any more for any more?
