400’000€ yearly income is not middle class. It is roughly the top 1%. Are you maybe mistaking property for income?
I would have preferred taxing on property instead of income, but as long as interests and profits and other benefits are part of income, it sounds reasonable to me.
Are you sure? Doesn’t the “smart edison bulb” design make it harder to dissipate heat to the casing, therefore making the LEDs get hotter compared to PCBs with LEDs surface mounted on them?
Anyway, if you want your
light bulbsany technology to last long, don’t buy the “smart” variant. “Smart” usually means more components and/or more dependencies on interfaces, and more complexity, so a higher chance to fail.
