Than getting something for nothing

I'll have my lion's share
Some will tell you that nothing's for free

I live the life, the life O'Riley
I've got so much time to spare
You can have your cake and eat it too

You think you're being cheated, you don't have a clue

Because I know in the future day
I sit in my easy chair
Because I know in the future day
And there's lots of free lunch for you
I live the lifestyle they speak of so highly
There's nothing that I like better
I live the life, the life O'Riley
Obviously they've not met me
Jump in, jump in
I'll have my lion's share
I live the lifestyle they speak of so highly
You don't know what to do
