The article explains where the money is going:
Expenses/savings (2013)
Income taxes $55,000, support for child and second Ontario home $47,500, overseas housing $52,500, retirement and other savings $20,000, meals and entertainment $24,000, church donation $18,500, cost of visits back in Canada $12,000, gifts to parents $4,800, life insurance $3,100, transportation $2,400, clothing and personal care $2,400, communication services $2,200, miscellaneous $2,300. Total: $246,700.
If they had only one home and didn't travel their expenses wouldn't be so bad. If they retired to the Canadian home they would reduce expenses by $64,000 a year. Are they literally spending $12,000 on airfare to and from Canada? Since they have a home there, they can't be spending it on lodging! That would allow them an additional $30,000 of savings I'd bet.
The meals and entertainment at $24,000 are also a big budget suck. Seems like that could be reduced to a measly $1,000 a month and save them another $12,000.
The college kid might be just tuition since the total includes the tuition, support for the child, and an Ontario apartment.
