By artificially elevating people with welfare and affirmative action you rob them of the experience of hard work to life themselves up.

That logic only works if you are working towards ways to get rid of the biases, prejudice and barriers that they already face. You can't tie a weight around someone's ankle, throw them in the pool and say "why can't you swim as well as me?". Thats the reason these things come into play, because the system works for some people and against others. These are productive programs, and while they can be abused, are still productive means of making up for other obstacles you and I don't have to face.

This is where the term "cuck" comes from

You are very confused, government is about bettering society. If there is a policy that helps you personally but hinders society, its selfish of you to support it. If theres a policy that hinders me, but aids society, like raising my taxes to fund an improved education system which will increase the wealth of knowledge and productive workers in the economy, then thats a good thing, its not being a "cuck". I understand the fact some people support less government involvement, but thats just your philosophy. Your opinion is not the only one with merit, you can follow the lead of many other successful countries that prove less government is not better.

The Left wouldn't exist without these issues

That is a pretty distorted view. Let me assure you, these issues are very much real, just because you can not fully understand them from your little bubble does not mean they are not real. There will always be people with odds against them and people who use their power, to give themself more at the expense of others. My view (and I think many people on the left's view) is to always fight for the people who are treated unfairly and speak against those who are greedy and corrupt. Look up the term "empathy" and thats the key difference between me and you.

After 50 years of voting Democrat, where has that gotten the black community?

Actually pretty far, as you know they aren't segregated anymore and racism has gone down significantly and their quality of life is much, much better than it was 50 years ago. But that doesn't mean its perfect, they still have significant barriers thanks to a lot of the prejudice that conservatives seem to harbor. Democrats can't change the fact that police are told to target black people, and that drugs found in lower income areas carry harsher sentences for no valid reason, and that the criminal justice system treats people differently based on their race, and that schools and productive programs are not properly funded in these lower income areas. When you incentivize crime and then turn around and ask why poor people turn to crime, it shows a lack of insight to the root causes. It doesn't really matter if they vote democratic, as long as half the country is constantly working to undermine any productive steps to help these struggling groups. You mention Venezuela and Greece, why not mention Switzerland, Norway, Denmark, Netherlands, Sweden, Finland and Australia, all of which are listed in the top 10 happiest countries and all of which operate under heavily democratic policies. This capitalist, survival of the fittest, every man for himself, mindset that the right seems to have works great when you are already propped up by the current systems in place. But all it does is create an unhealthy society where some people are very well off and others are miserably doomed, and theres not a whole lot in the middle. This mindset has created the unhealthy society we have now with the largest income inequality we have ever had. The government's role is to improve society, that means creating an enviroment where everyone has an equal chance at success. Again all that I just typed out can be paraphrased as follows: I am empathetic, you are apathetic. Simple
