Better than you syndrome

It's thanksgiving and I have a lot to be thankful for, my kids, my girl, my family and the forward progress of my life.  There is one thing i'd like to discuss tho, some people even on one day out of the year, that is supposed to be about thanks and positive feelings and thoughts, that still some people just can't get over themselves enough to leave well enough alone.  I get to hear it every day just so they can hear themselves talk.  What gives anyone the right that has no job and has't shown any will to get one, after graduating, the right to tell someone who works full time and earns everything they have, how to spend their money and what they should and shouldn't have.  Also would like to know how you can be better than another person when they are the only one who can't have a conversation without bringing out negative false pieces of info and making up things negative about the appearance, life standing, intelligence, and position in life of to someone else, even when all the person intended the convo for was as simple as when will our children be dropped off after dinner? The one person uses please, thank you , be safe, and have a good day even through the constant derogatory remarks and nothing good that comes from the others mouth. I don't understand how someone can hate their path in life that they chose and are not willing to change, has to push their misery on every one around.  bridges do burn people keep it in mind.
