Historically, staking a lot of coins is a common thing. reducing it is impossible because its default mechanism is so and this game is only for the rich. That $ 5,780 symbolizes that you spend money to mine coins but you don't lose your electricity or land rental costs. you will be much more profitable and so will the business doing staking. So that is a very normal level.
If you're able to achieve ROI in the long run, then the 32 ETH requirement is fine. Then main issue would be ETH's price across the crypto market. At current prices, 32 ETH may not seem like much in terms of USD, but it could be a lot of money once prices start to rise on the market. While there's still the choice of staking pools, the profit you'll earn will never the same as staking with 32 ETH. We're still early from experiencing a PoS version of Ethereum, though. In the long run, devs could either decide to lower or increment the ETH requirement depending on the community's approval.
As many have said earlier, ETH will be a hybrid cryptocurrency which is a plus for maintaining decentralization. If it remains a hybrid crypto for the foreseeable future, people will have a choice to either stake or mine ETH greatly encouraging the decentralization of the entire network. Even the 32 ETH requirement seems to be much more affordable than 1000 DASH for a masternode. So I've figured that there may be no reason to worry about the staking requirements for ETH as long as the cryptocurrency remains self-sustainable for years to come. Just my opinion
