How is anyone supposed to better themselves? You'll have to flip an awful lot of burgers to pay off your mortgage and save for your pension.
I put away a little money every year. Now. The reason I do this is you don't wait to get handed your retirement, you think about it when you are young.
Because if you don't have your retirement worked out by the time you are 40, you've failed at life. That's harsh I know, but it's still true. You don't think about how to take care of yourself when you are old BEFORE you are starting to lose your knees you have failed at the big game of life.
There is no safe job you can count on forever, there is no magic path to economic surety, there is no government that will protect you from life. You plan, you prepare, and you hope.
It's fine the right preaching self-reliance, but if they take away peoples' means of acheiving it, then it won't work.
If the only job you can get is flipping burgers [and that's almost always not true, people simply lack the ability to "think outside the box" as much as I hate that phrase] you work two shifts. Harsh, but there you go.
That's not enough? Work 2 and get a part time job on the week ends. Work overtime. There's always a way. It's only a question if you are strong enough or smart enough to take it.
I have a job that pays ok. I put a little away. Things continue as they do, and assuming the economy is generally better in 20 years than it is now, I should have a house and a few million to throw around when I retire. Get a boat, point away from land, wait for death in style.
