Is gentrification a good thing or a bad thing?

Good for super capitalists and those able to afford more modern housing. Not so great for indigenous community members who are economically forced from a community they've resided in for generations.

The misuse of this term by the talking heads needs to stop.

Gentry: "People of gentle birth"
refers to (sic) "good breeding", or high social position from the upper (sic) "ruling class."

First of all the concept of a ruling class is absurd. There are extremely wealthy people and they do not move into those areas.

The successful middle class renovates and restores. City government urban planning to revitalize and restore sections of cities that fall into decapitated conditions often calls for razing unsafe structures or having empty structures repaired and often rebuilt.

That there are people who find this causes them inconvenience is highly unfortunate. However I can inform you that in the 1950s and 1960s the very same sort of displacement was going on to many in the middle class to create corridors for the interstate highway system. At potential massive economic setbacks and future losses.

Nobody much paid attention when someone lost their college fund back then. It was just the luck of having been living at the wrong address.

i don't like it but i think gentrification has been happening since the beginning of modern cities and are a natural process formed by many factors accidentally interacting with each other like when an area was built and the average time building materials take do degrade, the building speculation market and what it favors at the moment, geographical factors,what area is more "in" etc. my area is a good example: it used to be the artist area with the cheapest rent and coolest people. then it was a victim of its popularity, everyone wanted to live here so all the rich people started buying buildings and speculation made rents go up so much that it is now one of the most expensive areas in the city for rents, the artist have left and there are no cool people in the parks playing guitar, smoking weed and hanging out. used to be one of the most awesome places on earth . the parks are so boring now.

I think we should let poor neighborhoods stay poor

Bad. It pushes the problems I to a new area that didn't have them while driving up the costs of living.
