Let me say something a bit more controversial. I'll start with realtors, so you will understand what I'm thinking.
It wasn't that long ago that a typical home sale in my community would have been in the $500,000 range. Realtors want a 6% commission to list a home for sale. But now real estate prices have skyrocketed, and many homes in my area are in the $800,000 to 1 million range. Is the realtor working that much harder now to earn that larger commission? Is the commission on a home sale really worth the amount they are now asking?
If we switch to restaurants, it wasn't too long ago that 2 people could eat out for about $20-25 (without alcohol). Now it's more like $40-50 for a restaurant meal (no alcohol). At the same time, the minimum wage has risen.
I'm still tipping at least 15%, but am I getting service now that's really worth 15% of $40-50 compared to the service I used to get just a year or two ago for $20-25? Frankly, I think the level of restaurant service that we're getting these days is poorer than in the past. They bring us the meal and then shortly after slap the check on the table. The wait staff often doesn't return to see if we need anything, such as a drink refill. (I'm in California. Maybe it's different elsewhere in the US.)
In Europe, service staff are well paid, and it is customary to tip less. So should we be tipping less in the USA?
We're eating out far less often these days. The cost is getting ridiculous.
