Interested to know views, as DH and I differ slightly. This may be as we have different family experiences!
DC(23) is pursuing a performing arts career. Has done training and is now getting established. Living at home, with us currently supporting by paying food etc, not charging rent, but not paying them any allowance any more. They are currently running down savings from previous work for their gym/ going out etc.
It's an industry where you have to invest a lot of time and effort in the early years, often for no (unpaid) or little return. The more time and effort you can put in, the more you are likely to be successful/ make useful contacts etc. Also you're expected to 'make your own work' i.e. your own shows and films etc.
Most actors need to have day/ 'survival' jobs in bars/ shops/call centres, but of course any time spent doing that is time NOT spent investing in their chosen career, makes auditioning hard etc, so the likelihood of success reduces. This is basically why it's so hard for working class actors to break through.
So, if as a parent, you were in the extremely fortunate position to 'fund' your DC for e.g. three years, to get the best possible start to their career, would you?
Or would you insist that they get a 'day job' for at least some of the time? Why?
