......” poor people are the most frequent smokers in my experience. Maybe that’s what keeps them poor”.....
Actually it often helps poor people ‘endure’ being poor. Calms the anxiety and tension of it all.
Wealthier people often drink alot to drown the pressure of sustaining their wealth.
Also eats up money and time, smells up clothes and breath, making it harder to find gainful employment, thereby adding to the stress that turned them towards smoking. Vicious cycle.
