Some days I do feel like this too, and feel terrible for bringing a child in to this world (hello PMT!), although when you really look at the past, things are better in some ways and acts of kindness happen around you all the time, but we are bombarded with so much negative media, it seems like things have never been so bad. I'm worse when I look at what other people have (a house with a garden that they own, great career with a big salary, another child (have to stop at 1 for financial and practical reasons), but then others might want what I have (rented flat with a nice view, allotment to grow own veg, a job which doesn't carry a huge amount of responsibility).
I work on a psych unit. You really do need to have empathy to accept being called names sometimes. It does make me angry when people bang on about people claiming benefits all of the time and "scrounging". A lot of people have been subjected to traumatic abuse throughout their childhood and adult life, and their self esteem is on the floor. I agree that the process to recovery and being independent is taking responsibility, but when you've had no guidance from a responsible adult through your life, it makes it more difficult to know where to start to get your life on track. They have no idea what you need to do to function or what normal is and that isn't their fault. Some people I have worked with will never work because they are so debilitated by their illness, and they don't respond to medication.
I agree that some people do exploit the system though. I think it is just one of the quirks in human nature that some people are like that. The majority of people generally have empathy for others and want to provide for themselves, but we all have flaws and bad days, and we have to be more selfish in order to get our shit together!
Many of our public services rely on people to have empathy. They just wouldn't function otherwise. Sometimes the fact that our services are stretched means it doesn't come across like that, but trust me, working in a caring profession and not being able to care is hugely frustrating.
I think the best thing to do is just concentrate on your day to day life and ignore the BS in media(although yes, I'm very much bricking it over Brexit), and remember, people do get through difficult times and carry on.
People have extreme opinions now because they are unhappy. When people are unhappy, they have to be a bit more selfish to figure out the next step, so seem to lack empathy. I think it is interesting that people have protested against the status quo by maybe supporting a more extreme choice, only time will tell if it works in our favour. If you look at how things have panned out through the years, change always happens. It's up to you how much you let it affect you.
