Currently they are cheaper despite the financial support for fossils but back then it was not and not enough was spent on research

It's not so simple. They're cheaper than building non renewable, but are they cheaper than keeping the current plants running? Also, energy consumption keeps growing, and in many places, new generating plants using renewables usually only take care of the growth, and doesn't allow for room to take older plants out of operations. If we don't make huge efforts to reduce our energy consumption, I doubt we're going to get rid of non renewables so soon...

It wouldn't even be less. We'd just have to reign in the capitalist feeding frenzy a bit.

2000 brands of shoes? Advertising? 99% of our production is wasted.

Whoa there buddy. That would put my butler's butler out of a job. Also where does a person park their yacht if not inside another, larger yacht?

Honestly this is what I keep saying and everyone gets pissed when I do.

There's enough resources on this planet that every living human could live a decently luxurious life. But because we allow a small handful of us to hoard all those resources we have poverty on a global scale.
