This still lives on? Man, people sure buy in hard to a lot of bull#### they hear.
A liberal mindset is one where you don't do much of anything in America totally on your own. You owe your successes, at least in part, to the work and sacrifices and contributions of others. It's really not a controversial view, if one looks beyond the ridiculous soundbites and tries to understand what folks are saying.
Society makes a ton of success possible for folks, and in return society should receive a portion of the rewards - is more the liberal mindset. Like a silent partner who fronts you the money to start your own business when you don't have it yourself, society fronts you roads, infrastructure, court system, police, a military, IP protection, educated workforce, education system, housing, utilities, and generations of folks working to make products and systems better. So when someone starts their own business, they're using all of these resources society puts at their disposal. In return, society asks to also benefit from the successes of the company, so as to continue to "pay it forward" to others so they can also build and succeed.
The mindset is nowhere near as controversial as your talking points up there. It's a pretty reasonable view of how people can achieve success.
If a person can't achieve the same level of success in a tribal region in Africa as they can in America, you have to admit that in part the success is due to the society in which they live and the benefits derived from living in it.
So in large part, "you didn't build that" by yourself...you benefitted from all this other stuff in order to succeed. What's wrong with this mindset?
