I'll agree that it is harder to setup an office when you have the burden of a family on your shoulders. Dentistry is probably still one of the best professions to generate hard currency quickly. My experience may have been different, but traditional relationship dynamics have changed quite a bit and it isn't as expensive as getting a wife. High end meals a drop in the bucket + infrequent, buying a nice car to impress them reeks of cringey beta-male behavior (buy a car you like, because you like it for whatever reason, not because you want to impress others), and no, I don't have to give up my freedom/convenience. If they don't like it, they can gtfo, lol. Trying too hard puts you on the weaker end of the relationship dynamic. Enjoy the ride or get out.
The whole point of making a lot of money is so that I don't have to depend on anyone to double my income, support a trouble-free lifestyle, as my income should be sufficient to cover all my expenses and then some. In an independent scenario, you shouldn't have to depend on anyone to pick up your kids; hire a nanny/driver/people to pick up your kids, help them with their homework, cook for you, or do other tasks that you don't want to do. You could hypothetically hire/support a whole bunch of 18+ y/o sugar babies to do this for you for the cost of one wife and might pay for itself if you ever had to get divorced (cost of divorce >>> cost of support staff).
Edit: "High end" meals are overrated and "high end aka high priced" does not mean high quality. Enjoy the food that you like and if you like cooking, cook instead.
Traveling is not for everyone. It does get tiring, especially if you have to do it the traditional way. There are convenient and fun options, but they are expensive. FBOs are one option, LAX/ATL has the private suite, showers and lie flat beds make traveling a lot more comfortable. If you travel to Asia a lot, get APEC to expedite your customs arrival, if not, there's always airport services that make your arrival experience seamless (such as meet and greet, private lounge/customs, luggage sent directly to where you are staying, and so on...)
