Who said that?
We're just saying that people who work full time shouldn't need welfare to make ends meet while there is indeed more than enough wealth in the system for everyone to make ends meet and the top few percent is taking in all of the economic growth greedily.
Working full time at a Mcdonalds, unless a manager, will never be a good job. It is a beginner job.
Companies are about profit. Most people operate on a profit model unless it is for friends and family.
Prices of gas and goods going up increases price in the product. Labor costs and building costs can raise prices too.
Everyone wants a piece of the pie. In distribution every player takes a cut. Price rises down the chain to allow profit at each step.
If something starts eating at the profits it is natural for the business to look for cuts they can make.
