live in clover

To live without financial stress; to live in comfort or luxury. If only I could win the lottery, then I would be living in clover, instead of working three jobs to pay my bills. He's lived in clover his whole life, so it's no wonder he's finding it tough having to fend for himself for once.

in clover, to be/live

To prosper. This expression, with its analogy to cattle feeding happily in a field of clover, dates from the early eighteenth century. It occasionally has been put like pigs in clover, and, in twentieth-century America, rolling in clover. All of them mean “to live well.”
