It very much depends on what stuff you're talking about. Consumption and QoL are only loosely correlated. If we have a culture that values status signalling, everyone may might work harder to afford status signalling without any real benefit to their quality of life. Efficiency of consumption matters. The relationship between dollars spent to degree of life improvement is nowhere close to 1:1. Some purchases pay dividends in that sense while others come with hidden costs and fleeting benefits.
