Judging from my experience - restaurants are not. We have started cooking more since the beginning of the lockdown being able to cook during the time that would have otherwise been spent on commute. And we have saved a surprisingly large amount of money in the process.
Food isn't a right. Let's produce only organic super healthy food for 3x the price and save the planet from the global warming, pollution and everything. Everyone would win, right?
Who's going to decide which trip is useless and which is not? The market has clearly decided that it is more profitable (hence useful) to offer cheap flights in not-so-great conditions for mere mortals than elite service for few. And those with money can get better service if they need it anyway.
Mass killings of useless people would help stop global warming as well. Why don't do that and leave only those worthy of living. Great idea, isn't it?
What you say sounds more like "to hell with those beggars who can barely afford current fees. Air travel should become a luxury as it used to be in the past".
Go buy a ticket in business class if you want a better service and leg room. It also goes with that warm "I'm better than the tramps several rows behind" feeling.
They were reusing bottles not because they were so conscious of the environment but because the country was dirt poor and could not afford producing enough new bottles.
And believe me, Warsaw's buses and trams are much more comfortable and less overcrowded than they used to be ever before.
