If you ask people what they want, they'll request some impossible combination of attributes without consideration of any tradeoffs.

They will also try to push all negative externalities on to people wealthier than themselves. Most people see themselves as middle class or lower middle class, even up to relatively high income levels. If you ask each of them where the tax rate should be increased, the answer is usually a few steps higher than their own income.

UBI is a topic where this becomes very obvious. When you explain UBI to most people they assume they will be receiving the UBI and some abstract combination of billionaires and corporations would pay for it. Then you show them the math that it wouldn't work and they start to become less enamored with the idea. (Or lately: They just don't believe you and retreat to their imagined ideal free of pesky economics)
