I think the expense of maintaining two households can be unnecessarily burdensome, even if you are making 6 figures.
How so? What burden is there when you have such means? I've met people who were Reservists who maintained timeshares for their weekends when they drill. Their Reservist pay just covers the cost of their weekend housing costs. Like I pointed out, even if we over-estimate $2000 a month rent and utilities for their secondary housing, that still leaves them with $150,000 of net yearly income, which still leaves them in the top 4% of income earners. If it's a burden at all, then they are not fit for the responsibilities of their job. Maybe a more unnecessarily burdensome expense if their outrageous salaries. Maybe Congressional pay should be reduced to $50k a year, and then we can talk about paying for their own rent being "unnecessarily burdensome."
Second, if providing for their own housing needs is too burdensome, then they need to do what the rest of Americans have to do when faced with the dilemma of having personal needs conflict with their ability to get to work every day. They need to reevaluate their situation and if necessary find another job that works out better for them.
