We don't need ...
More prestige buildings, office buildings, or similar, for a few “ego driven people”. They don’t even care for the sites, they only care for the funds given by the government, in other words, our tax money.
As nature itself, we need at least to balance the capitalistic system, in like establishing an Universal Basic Income. Instead of useless buildings, that stay empty most of the time anyhow. Building hospitals (renovating) and houses instead, that nobody anymore, only if wanted, have to sleep on the streets.
Don’t tell me we can’t, because all the “more or less” useless stuff is build all the time, with the excuse it generates jobs.
We have to concentrate on the important things a way more, I think and the majority don’t.
