I agree with SS that wealth creation is the key. I was saying to daughter 2 the other night that I have never felt as secure as since 15+ years ago I started working for myself, amazing though it sounds. I would need legions of people who pay me all to sack me to be in trouble rather than just one grumpy boss.
I have tried to ensure and will try that the children pick work where if they like in due course they can be their own boss in some way, that at least has the capacity for that. Even teaching can be that. Their father had 30 pupils plus his job etc and post as organist too. I earned as much from my own work than my employment in my last year of employment. We also had 2 flats we rented out at one piont. In other words putting eggs into lots of baskets can also protect you.
I also agree about pay. I deliberately picked areas women don't work in . If women are useless as driving pay upwards then those are the areas to avoid.
At at much more working class level there were huge equal pay cases fairly recently between women in the NE and men working for councils - every similar jobs and comparable but men getting all kinds of extra bonuses and extra pay. Illegal but it took brave women to bring claims and I think the result might have been veryone's salary reduced.
I agree that times change and what was well paid then may not be later although in general cleaners and care home workers will tend always to earn less than managing directors whether in 1860 or 2012.
Having wide skillls which can be pplied ni other areas helps too. I took on a small business in 2010 as well as my other stuff. I like having a good few things so if one stops working or isn't profitable there are other things too.
