If we're just going to attribute anything that happened during capitalism as a result of the "free market" then I get to say that communism invented satellites, discovered stem cells, and cured maternally transmitted HIV.

Electric cars and solar panels won't save us. You're not fooling anyone with that. Solar panels are not nearly efficient enough to replace anything major any time soon, and electric passenger cars will certainly help, but they are not hitting the pavement fast enough to have any kind of impact in the timelines we need to see to avoid apocalyptic catastrophe.

Also how will gas power plants help climate change? Unless this is a different use of the word 'gas' than i'm used to, I think you're referring to natural gas, aka: one of the largest contributor to carbon emissions.

And damn, I've heard a lot of dumb anti-socialist arguments before, but "people who are not able to provide labor to a market economy should starve to death" is a new one.
