If you have enough emergency savings then it can make sense, particularly when the majority of your income comes from stock. I'm talking about enough savings to live for a year or two even if you lose your job and your company's stock goes to zero. At really high incomes, especially with stock vesting only a few times a year rather than every month, you can operate more like a business than a month-to-month budgeter. Keep enough cash on hand to smooth out the spikes in income. If your income is high enough to do this, you won't have a problem building the initial cushion. What's irresponsible is living off your stock when you don't have that emergency fund.
