They made a career and life choice and their family treated them appallingly because of it.
In what way were they treated appallingly?
As you say, they made a career choice - so why should they expect to pick and choose a few aspects of the job which they preferred and expect to still receive the perks that went with a full-time position? It doesn't happen with other firms, other careers.
They made a life choice - absolutely fine, they emigrated, as many younger people do, but other people in their late 30s do not expect their parents to continue to fund the lifestyle to which they were accustomed. Harry seemed shocked that his father would not continue to pay to indulge his privileged life.
It's quite a reality check for them both.
