That is such a lazy argument. More people then ever before are out of poverty in the history of mankind. Doesn’t mean there are not problems. In regards to COVID, we took millions of people out of the workforce while printing money and still paying many of them? Of course that will result in massive reduction of inventory levels that we will feel for a decade. That results in inflation as what do people expect when less items available to the same amount of people that want them.
Regards to qualities etc. That varies. We have more access to products then at anytime in history as well. And many of these products have come down significantly in price. But that also means quality products and their prices get compared to shit products at lower prices. What do you think people buy? Secondary, people do far less informal work and that effects your perception of income. Our parents and grandparents maintained their own cars and houses for example and grew far more food. Now every hires that out and buys all their groceries at a store. That leaves you with far less money.
Then there is one industry that has made gains but their costs has gone up ten fold. That is healthcare. You have access to some of the best medical procedures then at anytime in history. But some of those costs can be North of a million dollars. Our parents and grandparents simply did not access that and in some cases died. I am happy I have now options but this is coming at a huge cost of which much of it has to be paid for upfront before you retire.
You could kill off every billionaire tomorrow but that won’t result in much more houses being built or available. Wealth inequality is an issue but if more cogs are not manufactured, our standard of living will not change much.
