In fact, you live better - far better - than anyone in history. It's not even close. It was built by the post-war 'neoliberal' order, on a foundation of human rights and free markets.
For us to quit and complain after all the work our predecessors did, remaining optimistic and working in a much starker situation - after depressions and world wars - would be pathetic abdication of our duties.
I suggest you read this:

Life is hard and always has been, but it's far easier than the lives of our ancestors (on average, of course).
Just look at the people who lived through - or the (200?) million who died in and more who lost everything in - WWII, less than 100 years ago, right after the Great Depression, right after WWI. And they were optimistic and energetic enough to build historically free, peaceful, and prosperous postwar order.
There is far more to do, absolutely. Let's get to work.
