I would modify the statement to "people who paid for themselves" instead of "own." But yeah, what one has to acquire and account for is always more valued.

some people dont care for anything though even stuff they paid for. when my dad was a much younger man and I was a small kid. every once and a while hed lose his temper and break something. He grew out of that past his 20s fortunately. But still when he reached a certain anger point he didnt care about his stuff even if he had bought it himself and wasnt well off to easily replace stuff. Some people either temporarily when they get upset or some people just as a general rule dont take good care of things.

Most people don't have much respect for other people's property. Compare a neighborhood where most people live in houses they own, to a neighborhood where most people are renting for someone else. Rented property is almost always abused and destroyed, but owned property is usually well taken care of. I am a home owner, and nearly every day, people walk or drive by and toss their empty beer bottles, soft drink cups, and fast food wrappers into my yard. I highly doubt that they ever throw their trash onto their own property.

Smokers are constantly using public beaches and parks for their ashtrays. You'll see discarded trash along most highways. The people who do these things are usually not tossing their crap on their own property.

I have over 500 DVDs. All are in like new condition. People ask to borrow them all the time, but I learned very quickly to always say no. Some people beg and plead, and I still say no. Why? Because every single time in the past that I loaned one out, it came back scratched, or so dirty that it had to be cleaned. I've received them back with pizza, peanut butter, jelly, and other stuff on them. I've received them back with the covers broken, or the paper stained with beer or coffee, or torn. I'd have to say that most people have zero respect for other people's property, and they simply don't care. Sure, there are exceptions, but the respectful people seem to be very rare.

Not necessarily. What changes peoples minds is being in the same situation as someone else. Walking a mile in their shoes. This story is as old as time itself.

For example: so many people walk on the flag because they never knew anyone who died defending it.

So many people treat fast food workers like shit because they never worked the job themselves.

I can go on and on. Some people never developed enough empathy foe their fellow human being to respect their things
They have to be shown how their assholes.

I always follow the golden rule. Treat others how I'd like to be treated. Same thing goes for other people's stuff.

Not always, of course; if you're given something as a gift by somebody you really care about, especially if you don't see them often, usually you'll take care of that! But that's the exceptional case.

It's like they always say; you can't buy integrity from somebody who has none to sell.

I quit weight lifting for that reason. Goon ass fucks like that.
