Yep I know a couple of people like this - all on good salaries but absolutely no financial sense.
I've had numerous clients like that over the years, whether on highly paid jobs or highly profitable businesses, and they spend like there's no tomorrow. I often inwardly cringe when I look at their accounts/bank statements to see the outflow of money.
One memorable one is a dentist earning over £100k per year who literally didn't have a penny in savings, not even a private pension, just relying on the NHS and state pensions for his retirement. Money went into his account and a month later it was all gone, rinse and repeat every month. Just literally dozens of payments out, for food, takeaways, clothes, etc. He curtailed his spending on approach to holidays so there was money in the account to pay for the flights and hotels etc, but it was still living month by month. He seemed to think the balance on his account was "spending money" and just spent it. Didn't even have an expensive house or expensive car to go with that kind of income.
Same with small businesses - some just spend like no tomorrow, especially on "image", such as having a brand new pick up truck every year, renting expensive "one man" office in a posh office block, etc. Just no need at all, but again, money in the bank burning a hole in their pocket, so spend just for the sake of it. Trouble is, they were in trouble when business dried up or customers didn't pay etc., as they had no savings and no room for "unforeseen" shocks.
Just relying that their incomes would never dry up and they didn't face unforeseen events with no plan B for what they'd do if things didn't turn out like that as they had no savings.
