Agree with Jane.
Had same conversation with my parents over Christmas, "we couldnt afford to go skiing when you was a child or go abroad".
I suppose they were right, only the elite went skiing in the 60's, infact I went for the first time in my 40's, but our kids now expect, nay demand, their week skiing and 2 weeks abroad in the summer.
ps, I am a self employed construction project manager.
