Values are deteriorating because the 'left' is and has been waging a relentless culture war for the last ten or twenty years - longer even, but they have upped the pace more recently. They control the media and academia and have been able to pass laws to make it so that even those who aren't totally brainwashed are unable to speak out because their lives could be destroyed as a result of it. On the flip side, the 'conservatives' are for sale to the highest bidder, so for the right price they won't stand in the way of the of these satanic plots.
The loss of religion in the west has also accelerated things, people don't have moral positions which they can cling to in order to fight what is going on.
Even people who practice a religion can't put up much resistance. We need look no further than our own community to see how many people support transgenderism and sodomy. Last year when a new abortion law was passed there were Muslims all over social media criticising the law and joinging the liberals in insulting people who don't think getting an abortion should be as easy as getting a hair cut. I'm sure we all remember the BLM riots, we also had Muslims cheerleading the destruction of people's personal property and joining the liberals in vilifying anyone who tried to put up a defence...the list goes on and on.
