San Francisco - How can one of the most beautiful cities in America turn into a rat infested piece of junk?

eAT tACO bELL. 

too many chinese and korean (polititians collapse) that lack of awareness of hygiene

How can you say that about the Democratic crown jewel?

All US cities are fully employed and fully exploited by corporations, but none are fully supported.

Liberals call this sort of situation "Progressive"

Normal people call it an environmental and Humanitarian nightmare.

I live in Oakland. Unlike San Francisco that's declining in beauty and economy, Oakland is getting new buildings (that don't tilt or crack), laying 100 miles of new pavement in the streets, and generally looking better every year.

And its violent crime rate has and continues to drop.

Lee and Bree have been terrible Mayors for SF. Under them, the streets have gotten fouled, crime has gone up, and the city actually smells of urine and feces in some areas.

No, this is Messina circa 1347, i.e. the perfect breeding ground for yersinia pestis, aka The Black Death. Under current management California won't act until tens of thousands are dropping dead in the streets. In L.A. thousands of homeless people die of preventable diseases every year, our city attorneys are calling in sick with Typhus and our cops are catching Typhoid Fever just from patrolling the areas around City Hall. The revered Rev. Andy Bales who's worked on Skid Row for years lost a leg to a flesh eating bacteria he picked up in the homeless encampments. It's beyond what one sees in third world countries. I have a relative who works for an AIDS NGO who spends most of her time around the sick in subcontinental Africa but won't set foot in Downtown L.A. right not.

The communist in SF call it progress

There are huge tent cities in Texas. Economy is bad for many Americans.
