I actually can see where you're coming from. I contemplated for a long time about my vote and realized even if I choose the candidate with more conscious values, I may still be overestimating both America's level of development and other countries. If we move too fast, conflict will inevitability occur. I think if you choose to vote based on this thinking, it would require some advanced statistical analysis that none of us have access to.
However if you vote based on intuition, I think the easy answer is Kamala. Although I think Trump is helping bring more blue Americans to stage orange thinking (and even beyond that in certain areas like him supporting weed legalization) , and he honestly strikes me as more authentic to himself than Kamala and I think because of this he can be swayed possibly with the help of Elon to create some kind of restructure of government that is uniquely industrious. But this is also risky.
Regarding policy, it's pretty obvious to me as young person that Biden's policies are significantly more conscious. His inflation reduction act was huge for shifting the American industry and economy to focus on renewable energy, which makes more sense long-term economically and for the environment. I have already seen the effects of this act in my city Seattle, with our improved transit infrastructure and we have more plans to do so. Trump and all republicans are against this act. But it is a perfect example of a good liberal policy, that focus on the future rather than the past.
Im getting a hint you live in blue/orange state or city since you mentioned fuel and grocery prices. You should do your own research into how you implement more renewable energy into your life, as this would save you a lot of money in the long term. That is just the culture where I live and it is exciting, we have huge electrical vehicle rebates and everyone in the city is excited about our transit plans , but I might have a different perspective if I was raising a family on a single income instead of a 20 year old college student.
