This stereotype goes back to the image of a Democrat being a trust fund kid who constantly lectures people on which pronouns to use. That's just not the case. If you were to take just a few examples of Republicans, you would say the same thing. These are people who got into politics because their family was wealthy. They never had to work for anything, and then they get into office and complain about people who want "handouts."
I hate people who criticize poor families who want food stamps, even though they were given everything to them. It's total hypocrisy, and honestly, I think you see it more on the Republican side. Most of these stereotypes are bon both sides, though they lean towards one side or the other. This one lands on Republicans if you ask me. Then again, I'm biased HAHA.
