while it's true that good health, genuine love & family harmony are priceless and cannot be bought by money, imho the poor leads a more miserable life because they have poorer care, welfare & opportunities. and there're many instances when wealth (which translate to influence, inside information & opportunities) can go a long way to make a miserable situation (like poor health) more bearable and to enhance one's potential and exploit opportunities (like shorting the English pound during Brexit and buying undervalue assets/property during this downturn).
show me a happy poor person and I can show you more than 10 happy rich persons.
just my honest, sincere opinion.
