Yeah, the guy in the M3 is enjoying his life so much more in stop/go traffic going to work.
Life is about enjoying every day, but it's also about making sure you can enjoy retirement and make sure you set your kids up to have a better life than you did. Wealth creation isn't done by buying expensive cars when you could invest the money. It figures though, you live in LI, that mentality is pervasive there.
I don't work with a single person who leases their cars and the average salary is probably ~350k. Top is in the several million. The most expensive car is a Panamera S Turbo. Most people who make ~500k drive Hondas, of the senior PMs, two drive Pilots, another drives an S4. That's it. One drives a 15yr old CRV. It's because they realize that wealth, and "enjoyment" isn't encapsulated in a depreciating asset that has no real utility beyond conveyance.
Part of the problem with America today is that too many people think like you. The big wealth aggregators are gone or are getting old, what remains are the short-term thinkers who would rather spend money than build it, enjoy it, and then pass it along to more aggregators who aren't spoiled but are driven to push forward.
Too many Paris Hiltons and not enough JP Morgans.
As far as child care - I've got that solved - my wife stays home. She could make more than we would pay in child care (Although with 4, who knows), but it's better than handing our kids off and letting somebody else raise them.
But too many people are too focused on their M3 than raising kids, or affording child care, or having a spouse stay home and raising kids. It's all "me me me me me". I know a number of people who would rather send their kids to a worse ranked school, pay less in property taxes, and drive a "nice" care. "me me me me me". Pretty sad really.
