Any or all of those could be in play. However, 2 of them can flip around and go the other way too. For example, inflation can be halted by the masses deciding the money matters more to them that the things they want to buy that they don't absolutely need. If the masses "just say no", pricing will magically start coming back down trying to entice them. In general, sellers want the cash even more than buyers want the products. However, right now there is still too much "I'll just pay" (any price) mentality in play.
Currency exchange rates fluctuate both ways. So check again in another year and perhaps it will flip the other way and your currency vs. the dollar will be worth more... thus making this kind of purchase cost less.
Corporate greed tends to know no bounds as long as the "I'll just pay" mentality dominates their markets. Corporations are happy to charge as much as anyone will "just pay..." even somewhat obligated to do so per "maximize profits for shareholders" and "maximize their own bonuses" drivers. But again, if the masses decide that the cash is worth more than the non-essential stuff being offered at rising prices, prices will stop rising... and then start to slide in search of a level where the masses will be moved again to start swapping dollars for the stuff.
If the buyers do NOT ever decide their money is worth more than the price being asked for stuff- that is, buyers simply stay in "I'll just pay" mode or "I will whine a lot about high prices and then I'll just pay" mode, prices will only keep rising... as there is nothing tangible "punishing" those hiking prices for doing so. In fact, they are getting rewarded for finding ways to sell stuff at higher prices.
